I checked zk dump from master UI, there all 5 zk servers are appearing with
some stats.
Not always we are getting this exception, only in random intervals we are
seeing it.

Now i need to read data directly from the Region and process [Data

Hi All,
We are happy to announce the release of Kundera 2.9 .
Kundera is a JPA 2.0 compliant, object-datastore mapping library for NoSQL

during the loading of data in our cluster I noticed some strange behavior of
some regions, that I don't understand.
Scenario:
We convert data from a mysql database to HBase. The data is inserted with a put

Try to increase hbase.regionserver.fileSplitTimeout but put it back to its
default value after.
Default value is 30 seconds. I think it's not normal for a split to take
more than that.
What is your hardware configuration?
Have you run hbck to see if everything is correct?

Have you taken a look at the logs on the RegionServers during the period?
One possibility is compactions happening organically. If you were
sustaining a certain level of writes most of the time, I could maybe see
that every 3 hours enough store files build up to require compactions.

I'm afraid you will have to ask MapR then what is supported. MapR M7 is a
proprietary application. It is _not_ Apache HBase.

No, I'm joking. Phoenix will allow you to run SQL on HBase. After that, I
guess you can use any SQL editor and connect it, but I'm not sure. It's
working very well for what it's doing.
However, Pheonix is tightly linked to HBase. You odds to get it

don't understand why it's about every three hours
Available HBase API allows to compact table's regions independently.
It can be cron job, script or client application which connects to HBase
cluster, selects regions and trigger compaction,
but you have to write this piece of software yourself.
