Operation category WRITE/READ is not supported in state standby
Hi users
We adopt HDFS HA in our environment within Hadoop-2.2.0.After
failover,the original namenode comes out lots of ERROR log as [1]:
We do the failover serval times,other READ ERROR logs also come out[1] .
My questions:
1.When could the WRITE or READ error log come out
2.Is the WRITE or READ error log normal becase of the HA,Is there any
solution to avoid this?
We had copied the core-site.xml and hdfs-site.xml to the Flume config
dir ,just like what we had done within Hbase.Suppose to avoid this problem
,Unfortunately ,the error logs still come out.
Yet the hdfs.path has been changed to hdfs://*nameservice*/flume/...
