java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745) {code} HBASE-13437 has us actual execute a close on timeout -- before we'd mark connection closed but would never call close on it. A background chore is going around stamping Connections in the ConnectionCache as 'closed' if they have not been used in ten minutes. The 'close' can come in at any time..... In particular between the point at which we get the table/connection and when we go to use it: i.e. flush puts. It is at the flush puts point that we get the above 'AsyncProcess: Failed to get region location' (It is not a failure to find region location but rather our noticing that the connection has been closed). Attempts at reproducing this issue locally letting the Connection timeout can generate the above exception if a certain dance is done but it is hard to do; I am not reproducing the actual usage by the aforementioned client. Next steps would be setting up python client talking via thrift and then try using connection after it has been evicted from the connection cache. Another thing to try is a pool of connections on the python side...connections are identified by user and table.
