Hi all,
I'm looking for some real-world Mapreduce traces (jobhistory) to analyze
the characteristics. But I couldn't found any except for SWIM
https://github.com/SWIMProjectUCB/SWIM/wiki/Workloads-repository that
contains several traces from Facebook. However, they're incomplete and lack
job

I am curious about this, too.

Hi,all:
Namenode HA (NFS, QJM) is available in hadoop 2.x (HDFS-1623). It provides
fast failover for Namenode, but I can't find any description on how long
does it take to recover from failure.

Hi all,
I'm running jobclient tests(on single node), other tests like TestDFSIO,
mrbench succeed except nnbench.
I got a lot of Exceptions but without any explanation(see below).
Could anyone tell me what might went wrong?
Thanks!
14/03/17 23:54:22 INFO hdfs.NNBench: Waiting in barrier for:
]
localhost: namenode running as process 20544. Stop it first.
localhost: datanode running as process 20786. Stop it first.
Starting secondary namenodes [0.0.0.0]
0.0.0.0: secondarynamenode running as process 21074. Stop it first.
Is there a way to solve this?
Thank you in advance,

a different PID directory (I think its called HADOOP_PID_DIR)
every time you invoke them.
I instead prefer to start the daemons up via their direct command such
as hdfs namenode and so and move them to the background, with a
redirect for logging.

trying to understand why you might want to do that.

I modified sbin/hadoop-daemon.sh, where HADOOP_PID_DIR is set. It works!
Everything looks fine now.
Seems direct
whether it works.

Are you trying to implement something like namespace federation, that's a
part of Hadoop 2.0 -
