Two regionservers(My cluster is 7 regionsever / datanode) crashed, saying that
an file didn’t not exist,
and that a lease has expired (log detail below). Tried to find in this mailing
list. It seems different:
Hbase version: 0.90.3
HDFS version: cloudera 0.20.2+320
OS： swappiness :0 and ulimit :600000
HFDS: dfs.datanode.max.xcievers: 2047
I didn't see any Xciever count exceeded message.
The cluster run normally before I modified some parameters.
Parameters:
Heap size 8G -> 10G
Hfile block 64k -> 640k( Our cluster uses gz )
Should I make the timeout to 0 or bigger ?
