Hi,
I tried to use MR RowCounter to count the rows of a table with specific column
family. But it is not displaying correct result.
Command (Only Table Name as argument ): Hbase/hbase-0.90.3/bin/hbase
org.apache.hadoop.hbase.mapreduce.RowCounter Keyword
Output :
11/11/16 13:04:31 INFO mapred.TaskRunner: Task 'attempt_local_0001_m_000000_0'
done.
11/11/16 13:04:32 INFO mapred.JobClient: map 100% reduce 0%
11/11/16 13:04:32 INFO mapred.JobClient: Job complete: job_local_0001

11/11/16 13:05:34 INFO mapred.JobClient: Map output records=0
Table Describe command Output is :
TABLE => {{NAME => 'Keyword', FAMILIES => [{NAME => 'Info', BLOOMFILTER =>
'NONE', REPLICATION_SCOPE => '0', COMPRESSION => 'NONE', VERSIONS => '3', TTL
=> '2147483647', BLOCKSIZE => '65536', IN_MEMORY => 'false', BLOCKCACHE =>
'true'}, {NAME => 'Set', BLOOMFILTER => 'NONE', REPLICATION_SCOPE => '0',
COMPRESSION => 'NONE', VERSIONS => '3', TTL => '2147483647', BLOCKSIZE =>
'65536', IN_MEMORY => 'false', BLOCKCACHE => 'true'}]}}
Am I executing in wrong way or this is some bug ?
