You can use Time To Live (TTL) attribute for the table for this. You can read about it here https://hbase.apache.org/book.html#ttl

129793ms is a very long time indeed. I would suspect that the kernel is blocking the process and not scheduling it for some reason. I would look into kernel messages (like dmsg, /var/log/messages) etc for clues.

You can do this: - Manually kill the server server05 by issuing kill -9. This will cause the master to recognize that the server is dead, and will re-assign the regions that were hosted there. Also you can safely restart the master in a production env. Nothing in Hbase client depends on master being available, in regular read / write paths (only DDL statements). Master is pretty light and will come up quikly, so you can restart masters safely.

If you read the exception, it clearly says what is wrong: NoSuchColumnFamilyException:Column family id does not exist in You have to have a column family in the mapping of column id. Also, I'm not sure whether using >8 column families is the right design. Unless you really know that you need column familiies for the IO pattern, just stick to one. Enis

How many disks you have per node? Can you please check the region server logs about compaction related logging? Everytime a compaction runs and finishes, there should be some log saying how much data is compacted and how long it took etc. There seems to be something misconfigured in your environment.

ZooKeeper has SSL with Netty. But I am not sure it is tested well. https://cwiki.apache.org/confluence/display/ZOOKEEPER/ZooKeeper+SSL+User+Guide @Josh, in case of HBase tokens, I think they are stored in ZK. Can this be a concern?

You should close the Connection / Admin / Table WHEN you are done. According to #3, Connection creation is very costly, so you would want to share the connection as much as possible, which means that you won't be "done" with the Connection until the application shuts down. Close the Connection when you know that you won't be doing any more requests. However, Table and Admin is relatively cheap, so you should open / close those per request.
