Hudson commented on HADOOP-14976: --------------------------------- SUCCESS: Integrated in Jenkins build Hadoop-trunk-Commit #13322 (See [https://builds.apache.org/job/Hadoop-trunk-Commit/13322/]) HADOOP-14976. Set HADOOP_SHELL_EXECNAME explicitly in scripts.

E.g. when > invoking _hdfs datanode_, the options variable name is inferred as follows: > {code} > # HDFS + DATANODE + OPTS -> HDFS_DATANODE_OPTS > {code} > This works well if the calling script name is standard {{hdfs}} or {{yarn}}. > If a distribution renames the script to something like foo.bar, , then the > variable names will be inferred as {{FOO.BAR_DATANODE_OPTS}}. This is not a > valid bash variable name. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
