Eric Newton commented on ACCUMULO-1824:
---------------------------------------
# I'm trying to explain what someone like me is looking for on the other side
of the ticket.
# We rely on users to be almost inhuman in their ability to communicate details
and chance observation. We should probably fix that.
# I clearly want to disambiguate rumor and hand-waving from digestible
problems. Though, I am clearly responsible for posting ambiguous and
unreasonable tickets myself.
# I want to document: we will read 4G of log files. Well, not me, but my
computer will. (Maybe don't push it to Apache's infrastructure.) I will spend
days fixing your problem if you give me the information.
> How to Make a Good Bug Report
> -----------------------------
>
> Key: ACCUMULO-1824
> URL: https://issues.apache.org/jira/browse/ACCUMULO-1824
> Project: Accumulo
> Issue Type: Wish
> Environment: meatspace
> Reporter: Eric Newton
> Priority: Critical
>
> h3. Details are incredibly important when making a bug report.
> * Provide a reproducible test case:
> ** unit test, or integration test preferred
> ** step-by-step instructions
> * Provide evidence:
> ** logs
> ** transcripts of following step-by-step instructions
> * What version of accumulo are you using?
> ** tagged version: provide the tag, ie. 1.4.2
> ** branch: provide the hash from the last pull
> * What versions of dependencies are you using:
> ** zookeeper
> ** hadoop
> ** jvm
> ** operation system
> * How many cores, how much memory, how many disks?
> * Is this a virtual machine? Is it running on a commercial cloud?
> * What have you changed in the configuration?
> * Have you reverted local code changes and re-tested?
> * Post every detail you can think of:
> ** config files
> ** test runs
> ** cluster size
> ** hdfs disk usage at the time
> ** load average
> ** phase of the moon (kidding!)
> *** except if something happens periodically ... include the period of time
> *** with specific measurements: "see attached graph"
> ** jstack stuck processes
> ** provide relevant OS settings
> *** "I have set swappiness to zero as suggested in the README"
> *** "No swapping was observed, here's the output of free..."
> *** "The file descriptor limit was set to 1024, but this is a single node
> instance."
> h3. Things to avoid:
> * lack of specific messages from logs, output, etc.
> ** "I think it said something about tablet not from mars... something like
> that"
> ** "it doesn't build... maybe missing some jar file"
> * frustration: "I updated to version 1.1 AND NOW NOTHING WORKS!?"
> * generalizations without details:
> ** in 1.2, I could create tables faster than 1.3
> ** servers seem to fail more often than before
> *** before what?
> *** what else changed?
> *** how can I reproduce your problem?
> h3. Cooperate
> Please provide the details if asked:
> * "Can you jstack the server next time and post it?"
> * Can you send your zookeepers the "stat" command and send the output?
> * When this happens, are you running a map-reduce job?
> * If you send me all your tablet server logs, I can probably figure out what
> happened
> * Are you seeing any errors on the monitor?
> * What version of accumulo are you running?
