What can corrupt HBase table and what is Cannot find row in .META. for table?

[Serega Sheypak]

hi, sometimes I do get im my web application log:
org.apache.hadoop.hbase.TableNotFoundException: Cannot find row in .META.
for table: my_favorite_table

I've found this
http://grokbase.com/t/hbase/user/143bn79wf2/cannot-find-row-in-meta-for-table

I did run hbase hbck
result:
0 inconsistencies detected.
Status: OK

What can I try next?
I'm using Cloudera CDH 5.2 HBase 0.98

Thanks!
