We experience the same type of issue. After a day or so clients stop being able to connect via jdbc, however connecting to hbase using the hbase shell works fine.
Likewise, there doesn't seem to be any log output indicating why, although I haven't spent much time trying to investigate. A restart of the hbase region servers seems to resolve the issue. 5 region servers 16gb heap each. No specific memory setting configured on the client, and effects clients from all machines.

Just a wild guess, but it sounds like it could be an OOM error. James On Monday, February 17, 2014, Russell Jurney <[email protected]> wrote: > Has anyone observed this behavior?
