DataNode Report Questions
HI:
I use hadoop version 0.20.2 . And I use fuse for nginx to read data.
Now there is 6 datanode in my cluseter.
And now I have a problem.
The log :
2013-04-10 18:10:25,007 INFO org.apache.hadoop.hdfs.server.datanode.DataNode: BlockReport of 1921511 blocks got processed in 39384 msecs
every time the Block Report , the nginx can not apply service .
I search a data,find that when Block is Report ,the hdfs read and write is be locked ,is this true?
I want to turn the Block Report intervel long , is it works? Or need upgrade the version to 1.0.4 ?
Thanks for your replying.
