Description

Local index is not created for a multi-tenant table however empty HBase table is created in advance for local index. With data upserted in the multi-tenant table, after multiple successive auto-splits when region tries to split again on another region server, LocalIndexSplitter prevents auto-split from happening. rajesh23 Please see the log below. Thanks apurtell and jamestaylor for narrowing down this issue.
