Ramon Wang commented on HBASE-9218: ----------------------------------- I had the same problem when i trying to execute a 'alter' command, here is the cmd: alter 'SPLIT_TEST_BIG', {METHOD => 'table_att', 'SPLIT_POLICY' => 'org.apache.hadoop.hbase.regionserver.ConstantSizeRegionSplitPolicy'} The split policy is not changed for table 'SPLIT_TEST_BIG', by digging the code, i found HTableDescriptor.getRegionSplitPolicyClassName in method HRegion.initializeRegionInternals always returns null. The HBase i'm using is 0.94.6-cdh4.4.0. > HBase shell does not allow to change/assign custom table-column families > attributes > ----------------------------------------------------------------------------------- > > Key: HBASE-9218 > URL: https://issues.apache.org/jira/browse/HBASE-9218 > Project: HBase > Issue Type: Bug > Components: shell > Affects Versions: 0.94.6.1 > Reporter: Vladimir Rodionov > > HBase shell.
