Changes how we do accounting of Connections to match how it is done in Hadoop.
Adds a ConnectionManager class. Adds new configurations for this new class.
"hbase.ipc.client.idlethreshold" 4000
"hbase.ipc.client.connection.idle-scan-interval.ms" 10000
"hbase.ipc.client.connection.maxidletime" 10000
"hbase.ipc.client.kill.max", 10
"hbase.ipc.server.handler.queue.size", 100
The new scheme does away with synchronization that purportedly would freeze out
reads while we were cleaning up stale connections (according to HADOOP-9955)
Also adds in new mechanism for accepting Connections by pulling in as many
as we can at a time adding them to a Queue instead of doing one at a time.
Can help when bursty traffic according to HADOOP-9956. Removes a blocking
while Reader is busy parsing a request. Adds configuration
"hbase.ipc.server.read.connection-queue.size" with default of 100 for
queue size.
