Ted Yu created SPARK-12181: ------------------------------ Summary: Check Cached unaligned-access capability before using Unsafe Key: SPARK-12181 URL: https://issues.apache.org/jira/browse/SPARK-12181 Project: Spark Issue Type: Bug Reporter: Ted Yu
For MemoryMode.OFF_HEAP, Unsafe.getInt etc. are used with no restriction. However, the Oracle implementation uses these methods only if the class variable unaligned (commented as "Cached unaligned-access capability") is true, which seems to be calculated whether the architecture is i386, x86, amd64, or x86_64. I think we should perform similar check for the use of Unsafe. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
