László Bodor updated TEZ-4097:
------------------------------
Description:
Currently, a fetch failure is reported like this:
{code}
2019-11-05 02:50:35,972 [WARN] [Fetcher_B {Map_4} #1] |shuffle.Fetcher|: Fetch
Failure from host while connecting: other_host, attempt: InputAttemptIdentifier
[inputIdentifier=1, attemptNumber=0,
pathComponent=attempt_1572936153637_0005_1_00_000000_0_10003, spillType=0,
spillId=-1] Informing ShuffleManager:
java.net.SocketTimeoutException: Read timed out
...
{code}
For debugging network/ssl/etc. issues on cluster, it would be convenient to see
the local host's name in these messages (which is present in the fetcher as
localHostname property), as in the logs collected by yarn cli, it's not obvious
for the first sight.
The same applies to FetcherOrderedGrouped, which reports something like:
{code}
2019-11-05 03:13:11,046 [WARN] [Fetcher_O {Map_1} #0]
|orderedgrouped.FetcherOrderedGrouped|: Failed to verify reply after connecting
to other_host:13562 with 1 inputs pending
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException:
PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to find
valid certification path to requested target
{code}
