Subject [jira] [Updated] (CASSANDRA-8192) AssertionError in Memory.java
Date Wed, 26 Nov 2014 00:37:12 GMT

Joshua McKenzie updated CASSANDRA-8192:
---------------------------------------
    Attachment: printChunkOffsetErrors.txt

([~alsoloplan]: are you the same person as [~Andie78]?)

Tried 7u71 here on 64-bit w/.bat file (no powershell), clean build of 2.1.1 and no changes
to any configuration files and I can't reproduce the above error.  I've also stepped all the
way down to a 32-bit 7u71 JVM w/a 256M heap, threw 5M rows against it via stress and ran a
major compaction in the middle of it and everything's behaving as expected.  Finally, as a
tiny sanity check, I took some data from 2.0.11 and loaded it into a 2.1.1 install, no problems.

Is this happening for you on a clean install of cassandra on this host without any data or
just on your existing dataset?  I'm attaching a patch that should print out the name of the
file the assertion error is getting thrown on as well as wrapping it as a CorruptSSTableException
rather than the non-informative assertion error.  It's possible you have a corrupt file as
our handling of invalid data in CompressionMetadata surrounding the chunkoffset size changed
in 2.1.

Please let me know what you see both with his patch and running a cassandra install w/out
data on this machine, and thanks for the info!
