---------------------------------------
Summary: ITestDynamoDBMetadataStore can leak (large) DDB tables in
test failures/timeout
Key: HADOOP-15888
URL: https://issues.apache.org/jira/browse/HADOOP-15888
Project: Hadoop Common
Issue Type: Bug
Components: fs/s3, test
Affects Versions: 3.1.2
Reporter: Steve Loughran
This is me doing some backporting of patches from branch-3.2, so it may be an
intermediate condition but
# I'd noticed I wasn't actually running ITestDynamoDBMetadataStore
# so I set it up to work with teh right config opts (table and region)
# but the tests were timing out
# looking at DDB tables in the AWS console showed a number of DDB tables
"testProvisionTable", "testProvisionTable", created, each with "500 read, 100
write capacity (i.e. ~$50/month)
I haven't replicated this in trunk/branch-3.2 itself, but its clearly
dangerous. At the very least, we should have a size of 1 R/W in all creations,
so the cost of a test failure is neglible, and then we should document the risk
and best practise.
Also: use "s3guard" as the table prefix to make clear its origin
