Subject Unable to find region for hello_world,,99999999999999 after 10 tries.
Date Wed, 15 Jan 2014 20:56:40 GMT
Versions of Hadoop 2.2, Hbase 0.96.1, Pig 0.12 that I'm using.

My problem is that whenever I run this script

raw_data = LOAD 'sample_data.csv' USING PigStorage( ',' ) AS (
listing_id: chararray, fname: chararray, lname: chararray );

STORE raw_data INTO 'hbase://hello_world' USING
org.apache.pig.backend.hadoop.hbase.HBaseStorage ( 'info:fname info:lname');

And the log show me this:

2014-01-15 20:12:30,788 [main-SendThread(hadoop-master:2181)] INFO
org.apache.zookeeper.ClientCnxn - Socket connection established to
hadoop-master/50.50.1.15:2181, initiating session 2014-01-15 20:12:30,798
[main-SendThread(hadoop-master:2181)] INFO org.apache.zookeeper.ClientCnxn
- Session establishment complete on server hadoop-master/50.50.1.15:2181,
sessionid = 0x14397878303000b, negotiated timeout = 90000

which seems OK, but after 10min, this error shows me:

2014-01-15 20:23:10,247 [main] ERROR
org.apache.hadoop.hbase.mapreduce.TableOutputFormat -
org.apache.hadoop.hbase.client.NoServerForRegionException: Unable to find
region for hello_world,,99999999999999 after 10 tries. 2014-01-15
20:23:10,250 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2999:
Unexpected internal error.
org.apache.hadoop.hbase.client.NoServerForRegionException: Unable to find
region for hello_world,,99999999999999 after 10 tries.

To check if everything is OK, I typed this command to check: hbase hbck and
give me this:

Summary:
  hbase:meta is okay.
    Number of regions: 1
    Deployed on:  hadoop-master,60020,1389816680166
  hello_world is okay.

    Number of regions: 1
    Deployed on:  hadoop-master,60020,1389816680166
0 inconsistencies detected.
Status: OK

In jps, my cluster give me the HRegionServer and HQuorumPeer in master,
Hmaster on my master

My jps master:

29660 ResourceManager
29264 NameNode
32372 HRegionServer
32064 HQuorumPeer
32159 HMaster
586 Jps
29513 SecondaryNameNode
31728 JobHistoryServer

My jps slave:

29817 Jps
29071 HRegionServer
26844 NodeManager
26665 DataNode
28731 JobHistoryServer

Only error that give is the hbase hbck because It runs and close before the
zookeeper continue I think.

There's anything I'm missing?
