Applying a Patch
MapR patches are version-specific and cumulative. Each patch contains the code fixes that were included in the previous patch for that MapR version.
MapR version-specific patches are available here: http://package.mapr.com/patches/releases/
Applying a patch is a 3 step process:
When you apply a patch to the cluster, the patched files along with original files
(non-patched) are copied to the /opt/mapr/.patch folder. In the /opt/mapr/.patch folder, the
file ending with .O is the original file (non-patched) and the file ending with
.<patch_number> is the patched version. Therefore, if there is a file under
/opt/mapr/.patch/lib/, you can compare that with the corresponding file under /opt/mapr/lib/
by using the md5sum
command to verify that the patch was successfully
deployed.
