Hari Sekhon updated HDFS-7565:
------------------------------
Description:
It appears that my Windows 7 workstation is passing a UID around 4 billion to
the NFS gateway and the getUserName() method is being passed "-2", so it looks
like the UID is an int and is overflowing:
{code}security.ShellBasedIdMapping (ShellBasedIdMapping.java:getUserName(358))
- Can't find user name for uid -2. Use default user name nobody{code}
was:
It appears that my Windows 7 workstation is passing a UID in the 4 billion
range and parts of the code are using java int's so it looks like the UID is
overflowing and giving -2 :
{code}security.ShellBasedIdMapping (ShellBasedIdMapping.java:getUserName(358))
- Can't find user name for uid -2. Use default user name nobody{code}
