Hi ,

I can't remove file from HDFS

hdfs dfs -rm -r /user/hadoop/.Trash/180223212154/user/hive/warehouse/dbaa.db/tablea21519385391248/dt=2018-02-22

rm: Permission denied: user=hadoop, access=ALL, inode="/user/hadoop/.Trash/180223212154/user/hive/warehouse/dbaa.db/tablea21519385391248/dt=2018-02-22":impala:hive:drwxr-xr-x

1. i created the table on hive and user : hadoop

drwxrwxrwt - hadoop hive 0 2018-02-23 18:54 /user/hadoop/.Trash/180223212154/user/hive/warehouse/dbaa.db/tablea21519385391248

2, i inserted data to table:dbaa.tablea with impala ,so the folder like below.

drwxr-xr-x - impala hive 0 2018-02-23 19:33 /user/hadoop/.Trash/180223212154/user/hive/warehouse/dbaa.db/tablea1519385391248/dt=2018-02-22

my question is

How can i remove the folder:/user/hadoop/.Trash/180223212154/user/hive/warehouse/dbaa.db/tablea1519385391248/dt=2018-02-22

1. I tried remove it with user:hadoop

hdfs dfs -rm -r /user/hadoop/.Trash/180223212154/user/hive/warehouse/dbaa.db/tablea21519385391248/dt=2018-02-22

rm: Permission denied: user=hadoop, access=ALL, inode="/user/hadoop/.Trash/180223212154/user/hive/warehouse/dbaa.db/tablea21519385391248/dt=2018-02-22":impala:hive:drwxr-xr-x

2. I tried remove it with user:impala

hdfs dfs -rm -r /user/hadoop/.Trash/180223212154/user/hive/warehouse/dbaa.db/tablea21519385391248/dt=2018-02-22

You have a mixed up situation.

Try as user "hdfs" (the superuser of hdfs) and also add -skipTrash in your command.
