[jira] [Commented] (SOLR-12083) RealTimeGetComponent fails for INPLACE_UPDATE when Cdcr enabled

JIRA jira@apache.org

    [ https://issues.apache.org/jira/browse/SOLR-12083?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16397501#comment-16397501 ]

Amrit Sarkar commented on SOLR-12083:
-------------------------------------

I have uploaded three patches with different designs:

1. add_support_for_random_ulog_in_tests.patch : This patch has nothing to do with the problem here but randomizing UpdateLog b/w 'UpdateLog' and 'CdcrUpdateLog'. We don't need to do 'HdfsUpdateLog' as it gets picked up anyway when directoryFactory is HDFSDirectoryFactory.

2. SOLR-12083-B-wo-test-framework.patch : This patch fixes the problem by randomising the UpdateLog b/w 'UpdateLog' and 'CdcrUpdateLog' within the {{TestInPlaceUpdatesDistrib}} which validates the fix I have put in place.

3. SOLR-12083-A-within-test-framework.patch : This patch extends the 'add_support_for_random_ulog_in_tests' with the fix in place.

> On the lines of SOLR-12063: Bidirectional support introduced serious bugs and here RealTimeGetComponent is broken.
> As we have added additional flag to each {{tlog}} entry, the following assertions fail when Cdcr enabled:
> {code}
> if (oper == UpdateLog.UPDATE_INPLACE) {
>  assert entry.size() == 5;
> }
> {code}
