我有一个10个节点的集群。当我提交Hive作业时，我得到以下错误-
WARN org.apache.hadoop.mapred.TaskTracker: Task Tracker local Incorrect permission for /data/gomz/mapred/local, expected: rwxr-xr-x, while actual: rwxrwxr-x
ERROR org.apache.hadoop.mapred.TaskTracker: Can not start TaskTracker because org.apache.hadoop.util.DiskChecker$DiskErrorException: all local directories are not writable
at org.apache.hadoop.mapred.TaskTracker.checkLocalDirs(TaskTracker.java:5268)
at org.apache.hadoop.mapred.TaskTracker.initializeDirectories(TaskTracker.java:907)

at org.apache.hadoop.mapred.TaskTracker.<init>(TaskTracker.java:2176)
at org.apache.hadoop.mapred.TaskTracker.main(TaskTracker.java:5310)
mapred-site.xml和taskcontroller.cfg中的mapred.local.dir都指向/data/gomz/mapred/local
对于我的Hive会话，我使用以下设置:
SET hive.exec.scratchdir=/dev/tmp/hive;
SET hive.metastore.warehouse.dir=/dev/warehouse; (setting works for Hive jobs that do not launch MR)
错误还可能指向哪些本地目录?
您可以检查/data的权限吗?
你能试试这个命令吗?
sudo chown $USER /data
执行完该命令后，再试一次
