nkeywal updated HBASE-5025:
---------------------------
Description:
There are two issues with these threads:
- there should have a better name. pool-x-thread-y is the default name given
by java.util.concurrent.Executors
- these threads should not survive to a minicluster shutdown
They are created by org.apache.hadoop.ipc.Server$Listener (with version
0.20.205.0; the code was different before), so the first issue is a hadoop
common one. It's unclear for the second one, it could be hadoop-common as well.
Constructor for org.apache.hadoop.ipc.Server$Listener:
{noformat}
public Listener() throws IOException {
//...
readPool = Executors.newFixedThreadPool(readThreads); // Lack a
ThreadFactory to set the names
//...
}
{noformat}
Server#stop shutdowns the thread pool.
