Possible issue when creating/deleting HBase table multiple times
Hello!
I'm using HBase 0.90.1-cdh3u1-SNAPSHOT. Running the attached code(adapted after sujee at sujee.net), after a while
I was getting the below exception. The main scenario is like this:
1. if table does not exist, create it
2. populate the table with some data
3. flush the data
4. close the table
5. disable table
6. drop table
7. repeat steps 1-6 for several times. After a while you'll get the mentioned error.
Please help.
Regards,
Florin

Want to file an issue Florin? Sounds like a bug that is easy enough
to replicate.

Hello!
Thank you for your responses. I'm working on 0.90.1-cdh3u1-SNAPSHOT. Yes,
if I have the following scenario:
1. disable table
2. delete table
3. create table
if I don't put the guard not(HBaseAdmin.tableExists(hbTable)) before creating rhe table (at step 3) the then it will end up in org.apache.hadoop.hbase.TableExistsException.
Regards,
Florin

Seems to be a CDH question.

And if you try to create it says its already there?
We have a job that does this over and over every few minutes and its
been running for months on end. I wonder whats different. You are on
0.90.3?
