[jira] Created: (HBASE-1570) HBaseClient.Connection.sendParam is not synchronized, which may lead to an NPE

HBaseClient.Connection.sendParam is not synchronized, which may lead to an NPE
------------------------------------------------------------------------------

                 Key: HBASE-1570
                 URL: https://issues.apache.org/jira/browse/HBASE-1570
             Project: Hadoop HBase
          Issue Type: Bug
    Affects Versions: 0.19.3, 0.19.2
            Reporter: Eugene Kirpichov


Suppose that two threads are concurrently calling HBaseClient.getConnection() to an address to which no connection has been made yet, or one existed but has been dropped due to an error.
One of the threads creates a Connection object, puts it into the 'connections' map, and there, starts doing before connection.setupIOStreams, goes a context switch
