------------------------------------
Summary: Document of "DistCp Guide" is wrong
Key: HADOOP-17933
URL: https://issues.apache.org/jira/browse/HADOOP-17933
Project: Hadoop Common
Issue Type: Bug
Components: documentation
Reporter: Jiahongchao
In [https://hadoop.apache.org/docs/stable/hadoop-distcp/DistCp.html,] it says
{quote}Now, consider the following copy operation:
distcp hdfs://nn1:8020/source/first hdfs://nn1:8020/source/second
hdfs://nn2:8020/target
With sources/sizes:
hdfs://nn1:8020/source/first/1 32
hdfs://nn1:8020/source/first/2 32
hdfs://nn1:8020/source/second/10 64
hdfs://nn1:8020/source/second/20 32
And destination/sizes:
hdfs://nn2:8020/target/1 32
hdfs://nn2:8020/target/10 32
hdfs://nn2:8020/target/20 64
Will effect:
hdfs://nn2:8020/target/1 32
hdfs://nn2:8020/target/2 32
hdfs://nn2:8020/target/10 64
hdfs://nn2:8020/target/20 32{quote}
However, since neither _{{-update}}_ or _-overwrite_ is used, _*first*_ and
_*second*_ directories** _**_ will be created
