[jira] [Updated] (CASSANDRA-8192) AssertionError in Memory.java
[ https://issues.apache.org/jira/browse/CASSANDRA-8192?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Joshua McKenzie updated CASSANDRA-8192:
---------------------------------------
Attachment: 8192_v1.txt
Looking at the raw data on these files, in both cases on the attached their file size is similar to the others however they are filled with 0's, meaning none of the parameters that CompressionMetadata needs to pull out are correctly set. This worked fine on 2.0.10 as we didn't query the chunkOffsetsSize during the constructor and only queried that data lazily - we changed our behavior to storing it at construction for CASSANDRA-6916.
On 2.0.10, a simple "select * from sstable_activity" should get you an exception that would uncover that you have corrupt data.
Attaching a patch for 2.1 to check for 0 chunks in a compressed file and throw an IOException if that's encountered.
