- I'm running Hadoop 2.4.0 tests on Ubuntu 14.04 on PPC64-LE .
- I've run about 4 times the Hadoop 2.4.0 tests and got 7 cores, 3 with Java6 (6.0_30-b30) and now 4 with Java7 (7.0_51-b31).
- Before Hadoop 2.4.0 , I was testing Hadoop 2.2.0 and got only 1 core (1.7.0_51-b31) with more tests runs.
- I'm compiling/testing Hadoop without Hadoop JNI code ( no -Dnative option).
- I've put the ulimit at some time and got 1 (big) core file.
- 
- All five Java7 cores look the same:
- - appearing in:
-    hadoop-hdfs-project/hadoop-hdfs
- - dealing with:
- Current thread (.....):  JavaThread "FSImageSaver for :
-   /home/tony/HADOOP/hadoop-2.4.0-src/hadoop-hdfs-project/hadoop-hdfs/target/test/data/dfs/name2
-   /home/tony/HADOOP/hadoop-2.4.0-src/hadoop-hdfs-project/hadoop-hdfs/target/test/data/dfs/name1
- 
- However, the cores made different Hadoop tests to crash.
- Running several times all the Hadoop tests shown that JVM crashes are random: the same elementary test may crash the JVM or run perfectly or output a Failure when run several times.
