Hbase master crashing

alex_eifler — Sat, 12 Nov 2016 03:56:08 GMT

After a cluster restart, hbase hangs and then crashes a few minutes after it starts. Here are some of the errors.

Check the state of the RegionServer before the Master reports this error. The Master is trying to read the hbase:meta table and failing. This should be a very fast operation.

This is the error log from one of the region servers. It seems to work for a few minutes, then the master crashes.

This hopefully is a bit more helpful. It looks like its compacting until the master crashes.

I was able to fix the problem by going into the the hbase zkcli and deleting the data under /hbase. Once that was deleted the hbase master and region servers started correctly.
