Corey J. Nolet commented on ACCUMULO-2944: ------------------------------------------ It looks like a pull request was merged in for this ticket. Can this be closed? > 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: 1.7.0, 1.6.3 > > 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.
