Dear all, My current HBase/Hadoop architecture has HBase region servers on the same physical boxes as the HDFS data-nodes. I'm getting an awful lot of region server crashes. The last thing that happens appears to be a DroppedSnapshot Exception, caused by an IOException: could not complete write to file <file on HDFS>. I am running it under load, how heavy that is I'm not sure how that is quantified, but I'm guessing it is a load issue.
Is it common practice to put region servers on data-nodes? Is it common to see region server crashes when either the HDFS or region server (or both) is under heavy load? I'm guessing that is the case as I've seen a few similar posts. I've not got a great deal of capacity to be separating region servers from HDFS data nodes, but it might be an argument I could make. Thanks Jamie
