jvm crashes intermittently during compaction
--------------------------------------------

                 Key: CASSANDRA-208
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-208
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: trunk
         Environment: arch: x86_64
os: Linux version 2.6.18-92.1.22.el5 
java: nio2-ea-bin-b99-linux-x64-05_feb_2009

            Reporter: Jiansheng Huang


jvm crashes intermittently during compaction. Our test data set is not that big, less than
10 GB.
When jvm is about to crash, we see that it consumes a lot of memory (exceeding the max heap
size).

The excessive memory usage during compaction is caused by the maintenance of blockIndexes_
in SSTable. this blockIndexes_ was only introduced to the apache version.
