Review request for accumulo, Sean Busbey and Eric Newton.


Use correct version of LogFile{Key,Value}

Bugs: ACCUMULO-2770

Repository: accumulo

Description (updated)

ACCUMULO-2770 Add utility to read local WAL

Forward port the upgrade code from 1.5.x into a separate utility so
that a user can still read local WALs if they happen to be around.
Recreate LogFile{Key,Value} in their old packages so that we can still
read the old sequence files.

Modify the utility to optionally accept values as command line options
instead of searching around in the configuration settings.

Add documentation to the troubleshooting guide to describe usage.

ACCUMULO-1264 move !METADATA file delete markers

Description: Move the !METADATA file delete markers out of the
  !METADATA table and to the root table on upgrade.
Author: Eric Newton
Ref: CDH-18697

Modified from commit 5416eef

ACCUMULO-1010 Support upgrades from 1.4 to 1.5

Description: Add steps necessary to move a zk from 1.4 state to 1.5.
  This leaves it in a good state to be picked up by the rest of the
  1.6 upgrade path.
Author: kturner
Ref: CDH-18697

Cherry picking caused a huge mess and it was simpler to manually select
the parts of the upgrade code that we needed based on the 1.5.1 tag.

Gathered from commits 317c669, aa6b4309, and 8811859.

CDH-18697 Add check for older versions

We need to detect
That the version is one four
To do an upgrade

ACCUMULO-2383 Add log4j properties support

Accumulo now looks for either XML or properties files for the Log4J configuration. It will
also heed the log4j.configuration isystem property if it is set. Its MonitorLog4jWatcher
can now load either properties or XML.

(cherry picked from commit cdcc1d4d41bf16e628b87893814a0ae9f627bcdb)

Reason: CM Compatibility

ACCUMULO-2343 Add AsyncSocketAppender

AsyncSocketAppender is a Log4J AsyncAppender with its own internal SocketAppender.
Configuration for either appender can be set on the AsyncSocketAppender itself. An
AsyncSocketAppender can be configured using a Log4J properties file, while an ordinary
AsyncAppender cannot.

(cherry picked from commit 5a72c37eadeca58e670517611f39824f4307321e)

Reason: CM Compatibility

Ref: CDH-17877

CLOUDERA-BUILD update plugin versions and properties.

* Updates plugin versions that are set by the apache root pom upstream
* Adds properties relied on that are set by apache root pom upstream

CLOUDERA-BUILD. Exempting temporary build/packaging files from RAT licensing checks

CLOUDERA-BUILD forward port example configuration files for CDH4 parcels and packages

Author: Bill Havanki <>

CLOUDERA-BUILD. Must work outside of the git branch the project lives in

CLOUDERA-BUILD Specify maven-plugin-plugin 3.2

The upstream maven-plugin module builds using maven-plugin-plugin 3.2, which is called
out in the Apache version 14 root POM. The CDH 4.6.0 root POM does not list the plugin,
and Maven 3.0.4 pulls down maven-plugin-plugin 2.9 instead (and complains that the
plugin version isn't specified, of course). The maven-plugin module build fails for
`mvn package` with the 2.9 plugin.

A bad workaround is to run mvn install first. However, that can cause builds to pull
older artifacts from the local repository instead of artifacts from the same build, via
the Maven reactor.

CDH-18855 use hadoop-tools instead of -distcp

There is no jar made
For M-R-1 Dist-C-P
So use tools instead

CLOUDERA-BUILD. Set cdh-root as parent pom.

Needed to modify some plugins to get a build to work:
 - Increment failsafe-plugin version
 - Increment assembly-plugin version
 - Exclude mockito from hadoop-common
 -- Mockito brings in a different version of Hamcrest than Junit
 - Explicitly define rat-plugin version
