Hi, All
Recently our Hbase (0.18.1) client stopped working.
The log contains the exceptions received from the server side:
DEBUG org.apache.hadoop.hbase.client.HConnectionManager$TableServers:
Attempt 8 of 10 failed with <java.io.IOException: HRegionInfo was
null or empty in .META.>.
Retrying after sleep of 32000
Client restart does not help. We did not try to restart the Hbase
cluster though.
We run the Hbase shell on the client host and entered "put", "get", "scan"
to read/write data from/to a table and run "scan .META." in the Hbase shell.
Sometimes the commands failed because of "RetriesExhaustedException"
but most of the time they run fine. It is strange that they are
inconsistent though.
I guess the .META. is missing, damaged or somehow unavailable (e.g.
b/c of permissions).
Do you know where the .META. is located ? How can I check if it is available ?
Thank for your cooperation,
M.
