Jimmy Xiang created HBASE-17625: ----------------------------------- Summary: Slow to enable a table Key: HBASE-17625 URL: https://issues.apache.org/jira/browse/HBASE-17625 Project: HBase Issue Type: Improvement Reporter: Jimmy Xiang
Tried to enable a table with 10k+ regions, it takes more time to generate the plan than do the actual assignment. This is so embarrassing. :) It turns out that it took quite some time to get the top HDFS block locations in registering regions when creating the Cluster object. There is no new region server, why do we need such info when trying to retain assignment? Is the region availability thing related to region replica? Can we avoid such penalty if region replica in not needed? -- This message was sent by Atlassian JIRA (v6.3.15#6346)
