What Ted said. This is for mailing list (Did you check the .out file? You are using a very early 1.7 version. Even the oracle fellas say you shouldn't use such early versions of 1.7.
> The process of disappear without any exception
> ----------------------------------------------
>
> Key: HBASE-7102
> URL: https://issues.apache.org/jira/browse/HBASE-7102
> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 0.94.2
> Environment: My HBase culster contains 7 computers. One is the master and zookeeper server, the other 6 are the region servers.
> The operatiing system is Centos 5.6 with kenerl 2.6.18-238.el5.
> The jdk version is 1.7.0_03
> Reporter: Jiuming Huang
>
> The culster is started normally. It can work when the I/O pressure is small.
> However, when I run a large pressure job (with a lot of threads, each of which writes and reads frequently) about one hour, one of the region server will crash.
> I investigated the logs of the HRegionServer, they didn't contain any exception log.
> Specifically, the log of the down server ends with some normal log (info level log).
> This bug can be replayed easily, and each time the crashed server is different. Even more, the log of the crashed server ends with different information for different experiment.
> I really don't know why the process of HRegionServer disappear so weirdly.
> If the process is crashed due to my configuration or the enviornment, the log should contain some exception information, right?
> So, I doubt the reason is the JVM crashed. But I didn't find any error log in JVM.
> How to go on the test to find the reason?
