Hi,
It seems that HBase 0.19 on Hadoop 0.19 fail to start because of exceeding
limit of concurrent xceivers( in hadoop datanode logs), which is currently
3000, setting more than 3000 xceivers is causing JVM out of memory
exception, is there is something wrong with configuration parameters of
cluster( three nodes, 430 regions,Hadoop heap size is default - 1GB)?
Additional parameters in hbase configuration are:
dfs.datanode.handler.count = 6,
dfs.datanode.socket.write.timeout=0
java.io.IOException: xceiverCount 3001 exceeds the limit of concurrent
xcievers 3000
at
org.apache.hadoop.hdfs.server.datanode.DataXceiver.run(DataXceiver.java:87)
at java.lang.Thread.run(Thread.java:619)
Any help is very appreciated,
Genady
