Sean Mackrory commented on BIGTOP-1362:
---------------------------------------
So on SUSE you just need nfs-utils, and on Ubuntu you just need nfs-common.
I'll add the appropriate package dependencies in a subsequent patch. The use of
hadoop-daemon.sh in the init script also needs to be changed as it emits a
warning that using that script to invoke hdfs is deprecated. To make this work
the following configuration is needed:
NameNode's core-site.xml:
{code}
<property>
<name>hadoop.proxyuser.hdfs.groups</name>
<value>*</value>
<description>
Set this to '*' to allow the gateway user to proxy any group.
</description>
</property>
<property>
<name>hadoop.proxyuser.hdfs.hosts</name>
<value>*</value>
<description>
Set this to '*' to allow requests from any hosts to be proxied.
</description>
</property>
{code}
NameNode's hdfs-site.xml:
{code}
<property>
<name>dfs.namenode.accesstime.precision</name>
<value>3600000</value>
<description>Access time for an HDFS file is precise up to this value.
Default value is 1 hour. 0 disables access times for HDFS.</description>
</property>
{code}
NFS Gateway's hdfs-site.xml:
{code}
<property>
<name>dfs.nfs3.dump.dir</name>
<value>/tmp/.hdfs-nfs</value>
<description>Needs to have enough space to buffer all out-of-sequence
writes</description>
</property>
{code}
And once the servers are started you can mount the filesystem with
{code}
mount -t nfs -o vers=3,proto=tcp,nolock <hostname>:/ /hdfs_nfs_mount
{code}
> Package NFS service for HDFS

> Yo Dawg, I heard Hadoop 2.3.0 included an NFS service, so Bigtop 0.8.0 should
> also contain an NFS service, so you can mount stuff while you mount stuff.
