---------------------------------------------------------------
This is happening due to FSUtils.getWALTableDir(),
{code:java}
public static Path getWALTableDir(final Configuration conf, final TableName
tableName)
throws IOException {
return new Path(new Path(getWALRootDir(conf),
tableName.getNamespaceAsString()),
tableName.getQualifierAsString());
}
{code}
Here it returns the table dir path without including "data" in path, so it is
creating namespace dir under the root dir when "hbase.wal.dir" not configured.
Simple fix will be,
{code:java}
public static Path getWALTableDir(final Configuration conf, final TableName
tableName)
throws IOException {
return new Path(new Path(new Path(getWALRootDir(conf),
HConstants.BASE_NAMESPACE_DIR),
tableName.getNamespaceAsString()), tableName.getQualifierAsString());
}
{code}
[~sreenivasulureddy] , are you working on this? Shall I prepare and attach the
patch?

> If HBASE_WAL_DIR if not configured, then
> recovered.edits dir path should be old method only.
> If user is creating x no. of tables, in different namespaces, then all are
> creating in the "hbase.rootdir" path only.
> {code}
> /<hbase.rootdir>/data/<namespace>/<table>/<regionDir>/recovered.edits
> eg:
> /hbase/data/default/testTable/eaf343d35d3e66e6e5fd38106ba61c62/recovered.edits
> {code}
> But the format is currently.
