We are also facing the same issue. Please tell us what is the solution. I
have increased the rpc timeout and caching is reduced but with no effect.
We are using hbase 0.98.7. Please suggest a work around as we are facing
the issue very frequently now and we are having downtime in production.

Glad you got it sorted out. Happy HBase-ing! :)

I'm also interested in an answer here. We see this from time to time in our
production HBase clusters (non-opentsdb). It seems to be related to
contention under heavy reads or heavy writes. But it's not clear what the
impact is here.

Hello Dima,
I figured out what it was. The problem was with the old znode which hasn't
been configured properly. I've removed /hbase znode (rmr /hbase) and
restarted hbase. Now it works properly.
Thanks again for the help
Sincerely,
Alexandr

Hey Alexandr,
What does your hbase-site and hdfs-site look like? Wanna upload them to
Gist or something similar and then paste a link?

Hello Dima,
Thank you for advice. But the problem haven't disappeared. When I start
HMaster on nn1 and nn2 nodes they work but when I try to connect to the nn1
(http://nn1:16010/) HMaster on nn1 crashes. HMaster on nn2 continue be
available via http://nn2:16010/ . Don't you know why it is happens?
Hi,
I'm currently testing Hbase 1.2.1 + OpenTSDB. For that, I'm generating a
high load of HTTP PUT on OpenTSDB, which then writes in Hbase. Currently,
I'm able to feed 300k data point per seconds, and I'm trying to achieve
higher speed.
I have also activate JMX on both Master and Region servers i
