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); Best regards, Vladimir Rodionov Principal Platform Engineer Carrier IQ, www.carrieriq.com e-mail: [email protected] ________________________________________ From: WangRamon [[email protected]] Sent: Tuesday, November 05, 2013 1:56 AM To: [email protected] 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!
