Fabian Deutsch commented on HADOOP-3895:
----------------------------------------
I don't know about a different way on debuging this, so I tried strace.
It hangs at "getdents64(3, ..." all the 180seconds.

> Key: HADOOP-3895
> URL: https://issues.apache.org/jira/browse/HADOOP-3895
> Project: Hadoop Core
> Issue Type: Bug
> Affects Versions: 0.17.1
> Environment: PowerPC using Fedora 9 (all updates) and OpenJDK-1.6
> Reporter: Fabian Deutsch
> Priority: Minor
> Attachments: hadoop-env.sh, hadoop-site.xml
>
>
> Hadoop starts, but eats 100% CPU. Data- and Secondarynamenodes can not
> connect. No jobs were run, just trying to start the daemon. using
> bin/start-dfs.sh.
> Using the same simple configuration on an x86-arch - also using Fedora 9 and
> OpenJDK-1.6 - works perfectly.
