[jira] [Comment Edited] (HBASE-9943) Big linked list test fails
with encoding PREFIX_TREE
[ https://issues.apache.org/jira/browse/HBASE-9943?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13824888#comment-13824888 ]

--------------------------------------------------------------
Here is a patch I used to simplify the actions and can reproduce the problem. You can see that even just restarting RS can cause the issue since I disabled all CM actions1 and actions2, and region move in actions3. It is not a decoder/encoder caching issue either since I disabled it.
Once you have a cluster, you can run itbll "hbase org.apache.hadoop.hbase.test.IntegrationTestBigLinkedList --monkey slowDeterministic Loop 5 12 25000000 IntegrationTestBigLinkedList 12" to reproduce it. The test won't survive many loops. It generally fails in loop 1 or 2 for me.

> ITBLL starts with encoding NONE. Online encoding change will try other encoding. However, if it starts with encoding PREFIX_TREE, the test fails, even with online encoding change disabled.
