Sean Busbey created HADOOP-11674: ------------------------------------ Summary: data corruption for parallel CryptoInputStream and CryptoOutputStream Key: HADOOP-11674 URL: https://issues.apache.org/jira/browse/HADOOP-11674 Project: Hadoop Common Issue Type: Bug Components: io Affects Versions: 2.6.0 Reporter: Sean Busbey Assignee: Sean Busbey Priority: Critical
A common optimization in the io classes for Input/Output Streams is to save a single length-1 byte array to use in single byte read/write calls. CryptoInputStream and CryptoOutputStream both attempt to follow this practice but mistakenly mark the array as static. That means that only a single instance of each can be present in a JVM safely. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
