Hi   I have 2 clusters both are in CDH 5.4.7   First cluster when I see the log file In HiveMetastore log, I see [pool-3-thread-xxx] every line in the log and In HiveServer2 log, I also see [HiveServer2-Handler-Pool: Thread-xxxxxx] every line in the log   But in the second cluster In HiveMetastore log, It didn't print [pool-3-thread-xxx] and In HiveServer2 log, It didn't print  [HiveServer2-Handler-Pool: Thread-xxxxxx]   So I want to see the pool thread in the log, I don't know why the first cluster show pool thread and second cluster didn't show    please suggest,  Any kind of help is appreciated.   Thanks, Teng       ...
