Hi,
I am using cdh4.4-mr1 for my scenario with Jobtracker HA.
During a failover of Jobtracker, the client is not retrying.
The root cause is:
The method:
org.apache.hadoop.mapred.JobSubmissionProtocol.getSystemDir() doesn't throw any
exception and when client failover happens on this API call,

Lei, perhaps hbase-user can help.

We have a dataset of ~8Milllion files about .5 to 2 Megs each. And we're
having trouble getting them analysed after building a har file.
The files are already in a pre-existing directory structure, with, two
nested set of dirs with 20-100 pdfs at the bottom of each leaf of the dir
tree.
LiuLei,
Using your example you can run umount -l /disk10 ( Lower case L ) on the disk
and it will lazy dismount and will not wait for a disconnect.
Thanks,

Hi Anfernee,
It sounds most likely that config somehow corrupts. So you have two sets of
config to start two YARN cluster separately, don't you? If you provide more
detail about how you config the two clusters, it's easy for the community
to understand your problem.

Hi Zhijie,
I agree, what I'm doing in the standalone app is that the app loads the
first cluster Configuration(mapred-site.xml, yarn-site.xml) as its default
configuration, and then submit MR job with this configuration to the first
cluster, and after the job is finished, I will submit the second

Hi,
I am planning to install Hadoop and Hbase in a 2 node cluster.
I have Chosen 0.94.16 for Hbase ( the current stable version ).
I am confused about which hadoop version to choose from.
I see on Hadoop's download page , there are 2 stable series, one is 1.X and
other is 2.X series.

Hi,
I have Hbase and Hadoop setup in pseudo distributed mode in production.
Now i am planning to move from pseudo distributed mode to fully distributed
mode ( 2 node cluster).
My existing Hbase and Hadoop version are 1.1.2 and 0.94.7.
And i am planning to have full distributed mode with Hbase
Both Hadoop 1 and Hadoop 2 work. If you start from scratch you should probably
start with Hadoop 2.
Note that if you want to use Hadoop 2.2.x you need to change the protobuf
dependency in HBase's pom.xml to 2.5.
(there's a certain irony here that the protocol/library we use to get version
20 matches
