Gaurav Kanade commented on HADOOP-12540:
----------------------------------------
The patch provides a new way to induce client error thus ensuring test
functions as expected. Instead of relying on the delete mechanism we simulate
the error now by creating a file, then acquiring a short lease on it and then
trying to write on it without the lease
> TestAzureFileSystemInstrumentation#testClientErrorMetrics fails
> intermittently due to assumption that a lease error will be thrown.

> HADOOP-12508 changed the behavior of an Azure Storage lease violation during
> deletes. It appears that
> {{TestAzureFileSystemInstrumentation#testClientErrorMetrics}} is partly
> dependent on the old behavior for simulating an error to be tracked by the
> metrics system. I am seeing intermittent failures in this test.
