Chris Nauroth updated HDFS-5995:
--------------------------------
Attachment: HDFS-5995.1.patch
This patch puts a soft cap on the size of the array that we pre-allocate in the
loader. I call it a soft cap, because it's still an {{ArrayList}} capable of
growing dynamically. This has eliminated the heap dumps in my environment.
It seems a shame to have to change the main loader code to accommodate the
test, but I haven't been able to come up with an alternative fix in the test
code.
> TestFSEditLogLoader#testValidateEditLogWithCorruptBody gets OutOfMemoryError
> and dumps heap.

> {{TestFSEditLogLoader#testValidateEditLogWithCorruptBody}} is experiencing
> {{OutOfMemoryError}} and dumping heap since the merge of HDFS-4685. This
> doesn't actually cause the test to fail, because it's a failure test that
> corrupts an edit log intentionally. Still, this might cause confusion if
> someone reviews the build logs and thinks this is a more serious problem.
