> Generated configuration files and scripts assume SUN as JVM
> -----------------------------------------------------------
>
> Key: ACCUMULO-2944
> URL: https://issues.apache.org/jira/browse/ACCUMULO-2944
> Project: Accumulo
> Issue Type: Sub-task
> Components: build
> Affects Versions: 1.6.0
> Environment: IBM JVM
> Reporter: Hayden Marchant
> Assignee: Hayden Marchant
> Fix For: 1.6.1, 1.7.0
>
> Original Estimate: 72h
> Remaining Estimate: 72h
>
> There are a few issues, detailed below:
> a. The generated configuration files contain references to GC
> params that are specific to Sun JVM. In accumulo-env.sh, the
> ACCUMULO_TSERVER_OPTS contains -XX:NewSize and -XX:MaxNewSize , and also in
> ACCUMULO_GENERAL_OPTS,
> -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 are used.
> b. in bin/accumulo, get ClassNotFoundException due to
> specification of JAXP Doc Builder:
> -Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl
>
> .
> The Sun implementation of Document Builder Factory does not exists
> in IBM JDK, so a ClassNotFoundException is thrown on running accumulo
> script
> c. MiniAccumuloCluster - in the MiniAccumuloClusterImpl,
> Sun-speciifc GC params are passed as params to the java process (similar
> to section a. )
> Single proposal for solving all 3 issues:
> Enhance bootstrap_config.sh with request to select Java vendor.
> Selecting this will set correct values for GC params (they differ between
> IBM and Sun), inclusion/ommision of JAXP setting. The
> MiniAccumuloClusterImpl can read the same env variable that was set in
> code for the GC Params, and use in the exec command.
> For exampel, doing this will result in CMS settings existing for SUN JVM, but
> when using IBM JVM, the relevant GC parameter for IBM JVM will be used
> instead. In addition, the SUN JAXP implementation will be omitted on non-SUN
> JVM.
> For now, I plan on having 4 options in new question
> 1. Sun
> 2. OpenJDK
> 3. IBM
> 4. Other
