Subject Re: [jira] Created: (HARMONY-6675) Reducing timeout value in CanonicalPatchCache to fix a file not found error in Hadoop common
Date Thu, 11 Nov 2010 05:13:44 GMT
The cache is good for the performance. But when the cache meet link, there
will be some difficult situation. The patch has attached is a workaround for
the specified test case. The good choose for the timeout should bed
discussed.
