Allen Wittenauer resolved HDFS-293. ----------------------------------- Resolution: Won't Fix Anyone still using 0.13 and earlier is probably living in a cave. > Remove code related to conversion of name-node and data-node storage > directories to the format introduced in hadoop 0.13 > ------------------------------------------------------------------------------------------------------------------------ > > Key: HDFS-293 > URL: https://issues.apache.org/jira/browse/HDFS-293 > Project: Hadoop HDFS > Issue Type: Improvement > Reporter: Konstantin Shvachko > Assignee: Raghu Angadi > > Hadoop 0.18 does not support direct HDFS upgrades from versions 0.13 or > earlier as stated in HADOOP-2797. > A 2 step upgrade is required in this case first from 0.x <= 0.13 to one of > version 0.14 through 0.17 and then to 0.18. > This implies that current hdfs does not need to support code related to > conversions of the old (pre 0.13) storage layout to the current one > introduced in 0.13 (see. HADOOP-702). -- This message was sent by Atlassian JIRA (v6.2#6252)
