When switching sessions this way, no change is made to the > original ticket cache so the cached filesystem instance doesn't get > regenerated. > > {{$ export KRB5CCNAME=/tmp/krb5cc_session1}} > {{$ kinit user_a@domain}} > {{$ touch /fuse_mount/tmp/testfile1}} > {{$ ls -l /fuse_mount/tmp/testfile1}} > {{ *-rwxrwxr-x 1 user_a user_a 0 Mar 21 13:37 /fuse_mount/tmp/testfile1*}} > {{$ export KRB5CCNAME=/tmp/krb5cc_session2}} > {{$ kinit user_b@domain}} > {{$ touch /fuse_mount/tmp/testfile2}} > {{$ ls -l /fuse_mount/tmp/testfile2}} > {{ *-rwxrwxr-x 1 user_a user_a 0 Mar 21 13:37 /fuse_mount/tmp/testfile2*}} > {{ }}{color:#d04437}*{{** expected owner to be user_b **}}*{color} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
