Hadoop-2.6.0 授权不适用于 MR 作业

Hadoop-2.6.0 Authorization not working for MR jobs

属性

<property>
    <name>security.job.client.protocol.acl</name>
    <value>kumar</value>
    <description>ACL for MRClientProtocol, used by job clients to
    communciate with the MR ApplicationMaster to query job status etc. 
    The ACL is a comma-separated list of user and group names. The user and
    group list is separated by a blank. For e.g. "alice,bob users,wheel".
    A special value of "*" means all users are allowed.</description>
</property>

我在cloudera文档中找到了答案here

看来 属性 security.job.client.protocol.acl 是针对 MR1 的,对于 MR2 我们可以使用 security.applicationclient.protocol.acl
