RE: How to change split policy of a specific existing table(not global)?‏
Shel does not support all table/column families attributes in 0.94.6

This should work:

HBaseAdmin admin = new HBaseAdmin(conf);
HTableDescriptor desc = admin.getTableDescriptor(Bytes.toBytes(SPLIT_TEST_BIG));// get your table descriptor
admin.disableTable(SPLIT_TEST_BIG);
desc.setValue(HTableDescriptor.SPLIT_POLICY, "org.apache.hadoop.hbase.regionserver.ConstantSizeRegionSplitPolicy");
admin.modifyTable(Bytes.toBytes(SPLIT_TEST_BIG), desc);
admin.enableTable(SPLIT_TEST_BIG);

Subject: How to change split policy of a specific existing table(not global)?‏

Hi Folks
I'm trying to change the default split policy of an existing table in HBase 0.94.6-cdh4.4.0. The way i think should work is by using HBase Shell, so i executed the following command in the SHELL:
disable 'SPLIT_TEST_BIG'alter 'SPLIT_TEST_BIG', {METHOD => 'table_att', 'SPLIT_POLICY' => 'org.apache.hadoop.hbase.regionserver.ConstantSizeRegionSplitPolicy'}alter 'SPLIT_TEST_BIG', {METHOD => 'table_att', 'MAX_FILESIZE' => '107374182400'}enable 'SPLIT_TEST_BIG'

But it doesn't work, only the 'MAX_FILESIZE' property get changed, the table still uses the default split policy which is 'IncreasingToUpperBoundRegionSplitPolicy', so can anyone tell me what is the correct way to do it, thanks!
CheersRamon
