Jerry He created HDFS-4943:
------------------------------
Summary: WebHdfsFileSystem does not work when original file path
has encoded chars
Key: HDFS-4943
URL: https://issues.apache.org/jira/browse/HDFS-4943
Project: Hadoop HDFS
Issue Type: Bug
Components: webhdfs
Affects Versions: 2.0.4-alpha, 1.1.2, 1.2.0
Reporter: Jerry He
Priority: Minor
Fix For: 2.1.0-beta
In HBase, the WAL (hlog) file name on hdfs is URL encoded. For example,
hdtest010%2C60020%2C1371000602151.1371058984668
When we use webhdfs client to access the hlog file via httpfs, it does not work
in this case.
