> Key: HDFS-7563
> URL: https://issues.apache.org/jira/browse/HDFS-7563
> Project: Hadoop HDFS
> Issue Type: Bug

> Affects Versions: 2.6.0
> Environment: HDP 2.2
> Reporter: Hari Sekhon
> Assignee: Aaron T. Myers
> Attachments: UID_GID_Long_HashMaps.patch

> When using the new NFS UID mapping for the HDFS NFS gateway I've discovered
> that my Windows 7 workstation at this bank is passing UID number 4294xxxxxx
> but entering this in the /etc/nfs.map in order to remap that to a Hadoop UID
> prevents the NFS gateway from restarting with the error message:
> {code}Exception in thread "main" java.lang.NumberFormatException: For input
> string: "4294xxxxxx"
> at
> java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
> at java.lang.Integer.parseInt(Integer.java:495)
> at java.lang.Integer.parseInt(Integer.java:527)

> {code}
> The /etc/nfs.map file simply contains
> {code}
> uid 4294xxxxxx 1yyyy
> {code}
> It seems that the code at
> {code}hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/security/ShellBasedIdMapping.java{code}
> is expecting an integer at line 318 of the parseStaticMap method: {code}int
> remoteId = Integer.parseInt(lineMatcher.group(2));
> int localId = Integer.parseInt(lineMatcher.group(3));{code}
> This UID does seem very high to me but it has worked successfully on a
> MapR-FS NFS share and stores files created with that UID over NFS.
> The UID / GID mappings for the HDFS NFS gateway will need to be switched to
> using Long to accomodate this, I've attached a patch for the parsing and
> UID/GID HashMaps.
