hadoop - AvroStorage以本地模式存储到hdfs中

Question

当我使用AvroStorage将存储路径的一部分指定为以“/”开头的输出路径时，即

STORE A INTO '/root/CustomerData-20160120-1101174' 
    USING org.apache.pig.piggybank.storage.avro.AvroStorage();

我收到一个错误:

java.lang.Exception: org.apache.hadoop.security.AccessControlException: Permission denied: user=root, access=WRITE, inode="/root/CustomerData-20160120-1101174/_temporary/0/_temporary/attempt_local1434837835_0012_m_000000_0/part-m-00000.avro":hdfs:hdfs:drwxr-xr-x
        at org.apache.hadoop.hdfs.server.namenode.FSPermissionChecker.check(FSPermissionChecker.java:319)

Pig脚本在-x本地模式下执行。当路径不带“/ root”时，一切正常。

STORE A INTO 'CustomerData-20160120-1101174' 
    USING org.apache.pig.piggybank.storage.avro.AvroStorage();

谢谢

它需要以file:/// ,, file:/// root /作为前缀...
