Masatake Iwasaki reassigned HDFS-15072: --------------------------------------- Assignee: Masatake Iwasaki > HDFS MiniCluster fails to start when run in directory path with a % > ------------------------------------------------------------------- > > Key: HDFS-15072 > URL: https://issues.apache.org/jira/browse/HDFS-15072 > Project: Hadoop HDFS > Issue Type: Bug > Affects Versions: 2.7.5 > Environment: I encountered this on a Mac while running an HBase > minicluster that was using Hadoop 2.7.5. However, the code looks the same in > trunk so it likely affects most or all current versions. > Reporter: Geoffrey Jacoby > Assignee: Masatake Iwasaki > Priority: Minor > > FSVolumeImpl.initializeCacheExecutor calls Guava's ThreadPoolExecutorBuilder. > setNameFormat, passing in the String representation of the parent File. Guava > will take the String whole and pass it to String.format, which uses % as a > special character. That means that if parent.toString() contains a percentage > sign, followed by a character that's illegal to use as a formatter in > String.format(), you'll get an exception that stops the MiniCluster from > starting up. > I did not check to see if this would also happen on a normal DataNode daemon. > initializeCacheExecutor should escape the parent file name before passing it > in. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
