netapp / netapp-hadoop-nfs-connector Goto Github PK

This is really a problem in the Hadoop code but it makes the connector unusable for most filers.
In CredentialsSys length is calculated like this:
mCredentialsLength = 20 + mHostName.getBytes().length;
However in linux/Unix (svc_auth_unix.c) the hostname's length is rounded up:
str_len = RNDUP(str_len);

This leads to the following error message in mountd when the host name has 33 chars:
bad auth_len gid 0 str 36 auth 53

How is this working in the Netapp filers?

Hi,
Were trying to use the connector to connect to a normal linux NFS share but receive the following exception:
