HI ，
I didn't try Hadoop rebalancer 。Because I remember rebalancer only considers
disk load, and won't consider that data blocks which rack 。
I can try 。Thank you for your reply 。

Hello,
I recently got Split metadata size exceeded 1000 error when running
Cascading jobs with very big joins. I found that I should change
mapreduce.jobtracker.split.metainfo.maxsize property in hadoop
configuration by adding this to the mapred-site.xml file:

Hey everyone ;
Could anyone tell me how to use the OIV tool in hadoop 1.0 as there is no
hdfs.sh file there.
Thanks.
It sounds like JobTracker setting, so the restart looks to be required.
You verify it in pseudo-distributed mode by setting it to a very low value,
restarting JT and seeing if you get the exception that prints this new value.

I'm getting this error while writing many files.
org.apache.hadoop.hdfs.server.blockmanagement.BlockPlacementPolicy: Not
able to place enough replicas, still in need of 4 to reach 4
I've set logging to DEBUG but still there is no reason printed. There
should've been a reason after this line but
The OIV for 1.x series is available in release 1.2.0 and higher. You
can use it from the 'hadoop oiv' command.
It is not available in 1.0.x.

Could I download the fsimage of a hadoop 1.0 using wget and then interpret
it in offline mode using the tool in the hadoop 1.2 or higher
distributions.I guess the structure of fsimage would be same for both the
distributions.

Sure, you could try that. I've not tested that mix though, and OIV
relies on some known formats support, but should hopefully work.

There shouldn't be any - it basically streams over the existing local
fsimage file.

Hi, all:
I configured a hadoop cluster with 9 hosts, each with 2 VCPU and 4G Ram.
I noticed when I run the example pi program, only when I configure it with
at least 8*9=72 mappers will all hosts be busy.
Which means there is a default 8 mappers per host?
How is this value decided? And where
19 matches
