We have a 6 node cluster, 5 with region serves. 2 of the region servers have
been stable for days, but 3 of them keep crashing. Here are the logs around
around when the crash occurs. (btw, we are shoving approximately the twitter
firehose into hbase via flume) I'm an hbase newbie, but I have been reading.
Not sure what else is needed to help debug. When the problem occurs, it is
concurrent with issues that appear all the way down in the data node. Also,
interesting to note, all 3 servers seem to fail differently somewhat:
Servers (6):
00.hadoop is the master
01.hadoop, 03.hadoop (there is no 02.hadoop - flaky machine that got taken out)
- are stable Region Servers
04-06.hadoop crash at different times, very different logs, Region Servers
