Hi all, I have tried using the HBase export/import tools to restore backup data in HBase without a success. The export works with relatively small data sets, but when there is around 2M rows, the map fails due to "RetriesExhaustedWithDetailsException: Failed 1 action". The problem is that I cannot find a real cause for this error. The region server just fails reading from the socket with "IPC Server listener on 60020: readAndProcess threw exception java.io.IOException: Connection reset by peer." after a while. I've played around with some of the parameters like hfile sizes, compression, max tasks, etc. but no improvements. Even though the exporting fails, all services stay up.
I'm running cdh3u2 on 1 master (namenode,jobtracker,master,zookeeper) and 3 slaves (tasktracker,datanode,regionserver) Log snippets Jobtracker: http://pastebin.com/zRt9Az4w Regionserver: http://pastebin.com/VHF4hYSp Zookeeper: http://pastebin.com/H0yS0iSG Any help highly appreciated! -- Petri
