+This example shows running a simple reservation system implemented using
+conditional mutations. This system guarantees that only one concurrent user can
+reserve a resource. The example's reserve command allows multiple users to be
+specified. When this is done, it creates a separate reservation thread for each
+user. In the example below threads are spun up for alice, bob, eve, mallory,
+and trent to reserve room06 on 20140101. Bob ends up getting the reservation
+and everyone else is put on a wait list. The example code will take any string
+for what, when and who.
+
+    $ ./bin/accumulo org.apache.accumulo.examples.simple.reservations.ARS
+    >connect test16 localhost root secret ars
+      connected
+    >
+      Commands :
+        reserve <what> <when> <who> {who}
+        cancel <what> <when> <who>
+        list <what> <when>
+    >reserve room06 20140101 alice bob eve mallory trent
+                       bob : RESERVED
+                   mallory : WAIT_LISTED
+                     alice : WAIT_LISTED
+                     trent : WAIT_LISTED
+                       eve : WAIT_LISTED
+    >list room06 20140101
+      Reservation holder : bob
+      Wait list : [mallory, alice, trent, eve]
+    >cancel room06 20140101 alice
+    >cancel room06 20140101 bob
+    >list room06 20140101
+      Reservation holder : mallory
+      Wait list : [trent, eve]
+    >quit
+
+Scanning the table in the Accumulo shell after running the example shows the
+following:
+
+    root@test16> table ars
+    root@test16 ars> scan
+    room06:20140101 res:0001 []    mallory
+    room06:20140101 res:0003 []    trent
+    room06:20140101 res:0004 []    eve
+    room06:20140101 tx:seq []    6
+
+The tx:seq column is incremented for each update to the row allowing for
+detection of concurrent changes. For an update to go through, the sequence
+number must not have changed since the data was read. If it does change,
+the conditional mutation will fail and the example code will retry.

+This example shows a simple map/reduce job that reads from an accumulo table and
+writes back into that table.
+
+To run this example you will need some data in a table. The following will
+put a trivial amount of data into accumulo using the accumulo shell:
+
+    $ ./bin/accumulo shell -u username -p password
+    Shell - Apache Accumulo Interactive Shell
+    - version: 1.6.0
+    - instance name: instance
+    - instance id: 00000000-0000-0000-0000-000000000000
+    -
+    - type 'help' for a list of available commands
+    -
+    username@instance> createtable input
+    username@instance> insert a-row cf cq value
+    username@instance> insert b-row cf cq value
+    username@instance> quit
+
+The RowHash class will insert a hash for each row in the database if it contains a
+specified colum. Here's how you run the map/reduce job
+
+    $ bin/tool.sh lib/accumulo-examples-simple.jar org.apache.accumulo.examples.simple.mapreduce.RowHash
-u user -p passwd -i instance -t input --column cf:cq
+
+Now we can scan the table and see the hashes:
+
+    $ ./bin/accumulo shell -u username -p password
+    Shell - Apache Accumulo Interactive Shell
+    - version: 1.6.0
+    - instance name: instance
+    - instance id: 00000000-0000-0000-0000-000000000000
+    -
+    - type 'help' for a list of available commands
+    -
+    username@instance> scan -t input
+    a-row cf:cq []    value
+    a-row cf-HASHTYPE:cq-MD5BASE64 []    IGPBYI1uC6+AJJxC4r5YBA==

+Accumulo has an iterator called the intersecting iterator which supports querying a term
index that is partitioned by
+document, or "sharded". This example shows how to use the intersecting iterator through these
four programs:
+
+ * Index.java - Indexes a set of text files into an Accumulo table
+ * Query.java - Finds documents containing a given set of terms.
+ * Reverse.java - Reads the index table and writes a map of documents to terms into another
table.
+ * ContinuousQuery.java  Uses the table populated by Reverse.java to select N random terms
per document. Then it continuously and randomly queries those terms.
+
+To run these example programs, create two tables like below.
+
+    username@instance> createtable shard
+    username@instance shard> createtable doc2term
+
+After creating the tables, index some files. The following command indexes all of the java
files in the Accumulo source code.
+
+    $ cd /local/username/workspace/accumulo/
+    $ find core/src server/src -name "*.java" | xargs ./bin/accumulo org.apache.accumulo.examples.simple.shard.Index
-i instance -z zookeepers -t shard -u username -p password --partitions 30
+
+The following command queries the index to find all files containing 'foo' and 'bar'.
+
+    $ cd $ACCUMULO_HOME
+    $ ./bin/accumulo org.apache.accumulo.examples.simple.shard.Query -i instance -z zookeepers
-t shard -u username -p password foo bar
+    /local/username/workspace/accumulo/src/core/src/test/java/accumulo/core/security/ColumnVisibilityTest.java
+    /local/username/workspace/accumulo/src/core/src/test/java/accumulo/core/client/mock/MockConnectorTest.java
+    /local/username/workspace/accumulo/src/core/src/test/java/accumulo/core/security/VisibilityEvaluatorTest.java
+    /local/username/workspace/accumulo/src/server/src/main/java/accumulo/test/functional/RowDeleteTest.java

+    /local/username/workspace/accumulo/src/server/src/test/java/accumulo/server/tabletserver/InMemoryMapTest.java
+
+In order to run ContinuousQuery, we need to run Reverse.java to populate doc2term.
+
+    $ ./bin/accumulo org.apache.accumulo.examples.simple.shard.Reverse -i instance -z zookeepers
--shardTable shard --doc2Term doc2term -u username -p password
+
+Below ContinuousQuery is run using 5 terms. So it selects 5 random terms from each document,
then it continually
+randomly selects one set of 5 terms and queries. It prints the number of matching documents
and the time in seconds.
+
+    $ ./bin/accumulo org.apache.accumulo.examples.simple.shard.ContinuousQuery -i instance
-z zookeepers --shardTable shard --doc2Term doc2term -u username -p password --terms 5

+This example uses mapreduce to extract specified columns from an existing table.
+
+To run this example you will need some data in a table. The following will
+put a trivial amount of data into accumulo using the accumulo shell:
+
+    $ ./bin/accumulo shell -u username -p password

+    - version: 1.6.0
+    - instance name: instance

+    username@instance> insert dog cf cq dogvalue
+    username@instance> insert cat cf cq catvalue
+    username@instance> insert junk family qualifier junkvalue
+    username@instance> quit
+
+The TableToFile class configures a map-only job to read the specified columns and
+write the key/value pairs to a file in HDFS.
+
+The following will extract the rows containing the column "cf:cq":
+
+    $ bin/tool.sh lib/accumulo-examples-simple.jar org.apache.accumulo.examples.simple.mapreduce.TableToFile
-u user -p passwd -i instance -t input --columns cf:cq --output /tmp/output

+This example uses map/reduce to generate random input data that will
+be sorted by storing it into accumulo. It uses data very similar to the
+hadoop terasort benchmark.
+
+To run this example you run it with arguments describing the amount of data:
+
+    $ bin/tool.sh lib/accumulo-examples-simple.jar org.apache.accumulo.examples.simple.mapreduce.TeraSortIngest
\

+    --maxKeySize 10 \
+    --minValueSize 78 \
+    --maxValueSize 78 \
+    --table sort \
+    --splits 10 \
+
+After the map reduce job completes, scan the data:
+
+    $ ./bin/accumulo shell -u username -p password
+    username@instance> scan -t sort

+Authorizations are sets of authorization tokens. Each Accumulo user has
+authorizations and each Accumulo scan has authorizations. Scan authorizations
+are only allowed to be a subset of the user's authorizations. By default, a
+user's authorizations set is empty.
