I'm a HBase newbie. Today I start to do stress test using 4 java process to load large amount of rows (1 minute = 18,000 rows). After a while, one of my region server log got this kind of WARN message:
WARN org.apache.hadoop.ipc.HBaseServer: IPC Server listener on 60020: readAndProcess threw exception java.io.IOException: Connection reset by peer. Count of bytes read: 0
1. What is the meaning of this WARN message?
2. I haven't check the data integrity, but is there any chance of data loss when encounter this WARN message?
For this stress test, I have 10 servers (with each server having region server and data node).
Only one server has that WARN message.
