Subject Re: [Query :] hbase rebalancing the data after adding new nodes in cluster
Date Thu, 20 Oct 2016 11:28:44 GMT
Hi Manjeet,

Probably because your table is not really deleted. Can you "list" the
tables to confirm? For the balacing, just run a major compaction of your
table and locallity will come back.
