> Key: TRAFODION-1212
> URL: https://issues.apache.org/jira/browse/TRAFODION-1212
> Project: Apache Trafodion
> Issue Type: Bug
> Components: sql-cmu
> Reporter: Weishiun Tsai
> Assignee: Suresh Subbiah
> Priority: Critical
> Fix For: 2.4

>
> The frequency of ‘drop schema cascade’ returning error 1069 is still pretty
> high, even after several attempts to address this issue. This is causing a
> lot of headache for the QA regression testing. After each regression testing
> run, there are always several schemas that couldn’t be dropped and needed to
> be manually cleaned up.
> Multiple issues may lead to this problem. This just happens to be one
> scenario that is quite reproducible now. In this particular scenario, the
> schema contains a TMUDF library qaTmudfLib and 2 TMUDF functions qa_tmudf1
> and qa_tmudf2. qa_tmudf1 is a valid function, while qa_tmudf2 has a bogus
> external name and a call to it is expected to see an error.
> After invoking both, a drop schema cascade almost always returns error 1069.
> This is seen on the r1.1.0rc3 (v0427) build installed on a workstation and it
> is fairly reproducible with this build. To reproduce it:
> (1) Download the attached tar file and untar it to get the 3 files in there.
> Put the files in any directory <mydir>.
> (2) Make sure that you have run ./sqenv.sh of your Trafodion instance first
> as building UDF needs $MY_SQROOT for the header files.
> (3) Run build.sh
> (4) Change the line “create library qaTmudfLib file
> '<mydir>/qaTMUdfTest.so';” in mytest.sql and fill in <mydir>
> (5) From sqlci, obey mytest.sql
> Here is the execution output:
> >>log mytest.log clear;
> >>drop schema mytest cascade;
> *** ERROR[1003] Schema TRAFODION.MYTEST does not exist.
> --- SQL operation failed with errors.
> >>create schema mytest;
