Jeffrey Manno (ASRC Federal) and Jeffrey Zeiberg (ASRC Federal) have discovered that adding a few new JVM options to the JAVA_OPTS set prevented crashing and increase system performance.
They were added after line 68 in accumulo-env.sh. They are: 'server' '-XX:+UseParallelOldGC' '-XX:NewRatio=3' '-XX:AggressiveHeap' The machines we are using are 7 year old machines with 8G of main memory, between 500G - 1T HDD and Intel I5 or I7 processors. Maybe these parameters should be made in the Accumulo 2.0 distributions accumulo-env.sh file? Comments?
