pre-commit not working?

[Vihang Karajgaonkar]

https://builds.apache.org/job/PreCommit-HIVE-Build/# does not seem to be
picking up new patches. I checked on the ptest server side and it seems to
be working fine. The build queue shows a weird "(pending—H14 doesn’t have
label Hadoop; H15 doesn’t have label Hadoop; "  message which I haven't
seen earlier. Also, https://builds.apache.org/job/PreCommit-Admin job is
showing the same message and in pending state since long time. Does anyone
know how do we fix this?
