Subject [jira] [Created] (HBASE-17625) Slow to enable a table
Date Fri, 10 Feb 2017 17:41:42 GMT

             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?
