sam commented on SPARK-1861: ---------------------------- OK, so what I need to do is ask my DevOps to upgrade our cluster to 5.1.0. > ArrayIndexOutOfBoundsException when reading bzip2 files > ------------------------------------------------------- > > Key: SPARK-1861 > URL: https://issues.apache.org/jira/browse/SPARK-1861 > Project: Spark > Issue Type: Bug > Components: Spark Core > Affects Versions: 0.9.0, 1.0.0 > Reporter: Xiangrui Meng > Assignee: Xiangrui Meng > > Hadoop uses CBZip2InputStream to decode bzip2 files. However, the > implementation is not threadsafe and Spark may run multiple tasks in the same > JVM, which leads to this error. This is not a problem for Hadoop MapReduce > because Hadoop runs each task in a separate JVM. > A workaround is to set `SPARK_WORKER_CORES=1` in spark-env.sh for a > standalone cluster. -- This message was sent by Atlassian JIRA (v6.2#6252) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
