Mehdi Salarkia commented on PHOENIX-5348:
-----------------------------------------
I'm not sure if this related or not. But from what I can see there 3 instances
of:
{code:java}
conn.createStatement().execute("DELETE " + " FROM " +
PhoenixDatabaseMetaData.SYSTEM_TASK_NAME);
{code}
in
{code:java}
org.apache.phoenix.end2end.DropTableWithViewsIT#testDropTableWithChildViews
org.apache.phoenix.end2end.IndexRebuildTaskIT#testIndexRebuildTask
org.apache.phoenix.end2end.index.IndexMetadataIT#testAsyncRebuildAll{code}
This couldn't be thread safe, right?
In addition to that I see
{code:java}
org.apache.phoenix.end2end.index.IndexMetadataIT#testAsyncRebuildAll
{code}
is also flaky which suggest it has to do something with the delete statement,
See
[https://builds.apache.org/job/Phoenix-master/2436/testReport/junit/org.apache.phoenix.end2end.index/IndexMetadataIT/testAsyncRebuildAll/]
{code:java}

What are the intents behind the delete statement above, is this to delete all
the task so this test can run faster?
