Use the 'DemoClient.py' which in this zip and write data through thrift2 server. When the python run more than 'hbase.thrift.connection.max-idletime', all connection to server will be interrupted, then thrift2 server did not work for a while and throw "hbase.ttypes.TIOError: TIOError(_message='Failed 1 action: IOException: 1 time, servers with issues: null location" to DemoClient.py. The problem is because when get table from HTablePools in ThriftHBaseServiceHandler.java, it never refresh the connection which in connectionCache. Until 'hbase.thrift.connection.max-idletime' come, connectionCache begin to clean connections which not refreshed. Then the problem raise. Problems appeared in the version 0.98. I will test this problem whether exists in branch 1+ or master. And sorry about the issue title. It is not a deadlock, it just because connection does not refresh when getTable. I added patch at the beginning of this year, mixed is up with another thing. was (Author: albertlee...@gmail.com): hbase-thrift-17906-ForRecurr.zip is made a little change of hbase-examples/src/main/python/thrift2 for recurring the problem.
