Hello, I have a very large HBase table running on 0.90, large meaning >20K regions with a max region size of 1GB. This table is legacy and can be dropped, but we aren't sure what impact disabling/dropping that large of a table will have on our cluster.
We are using dropAsync and polling HTable#isEnabled instead of the standard shell disable command to avoid a timeout during disable like in https://issues.apache.org/jira/browse/HBASE-3432. Is there any risk to overwhelming zookeeper or the master with region closed events during the disable, or would it be comparable to what happens during a cluster restart when RS closes out regions? Additionally, are there any concerns with wiping out that much data in HDFS at once during the drop? Thank you in advance, Michael --
