Subject [jira] [Created] (ACCUMULO-4486) Compaction from Shell hangs on Unknown property
Date Wed, 05 Oct 2016 17:35:20 GMT
Michael Miller created ACCUMULO-4486:
----------------------------------------

             Summary: Compaction from Shell hangs on Unknown property
                 Key: ACCUMULO-4486
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-4486
             Project: Accumulo
          Issue Type: Bug
          Components: shell, tserver
    Affects Versions: 1.8.0
            Reporter: Michael Miller
            Priority: Minor


I was following the sampling [example|https://accumulo.apache.org/1.8/examples/sample] when
I mistyped one of the table properties. After realizing this I entered the correct property
but didn't remove the bad one. I then ran the "compact" command but the shell hung indefinitely.
There was an IllegalArgumentException printed in the log but I believe the bug is how the
shell mishandled the exception, never returning control to the user. Eventually I did get
a warning on the shell "WARN : Thread "shell" stuck on IO.." but never regained control of
the shell. Here are the commands run:
createtable sampex
insert 9255 doc content 'abcde'
insert 9255 doc url file://foo.txt
insert 8934 doc content 'accumulo scales'
insert 8934 doc url file://accumulo_notes.txt
insert 2317 doc content 'milk, eggs, bread, parmigiano-reggiano'
insert 2317 doc url file://groceries/9.txt
insert 3900 doc content 'EC2 ate my homework'
insert 3900 doc uril file://final_project.txt
config -t sampex -s table.sampler=org.apache.accumulo.core.client.sample.RowSampler
config -t sampex -s table.sampler.opt.haser=murmur3_32
config -t sampex -s table.sampler.opt.hasher=murmur3_32
config -t sampex -s table.sampler.opt.modulus=3
compact -t sampex --sf-no-sample

Stacktrace of the exception printed in the tserver log:
