I would like to reopen an old topic, which is to introduce a Read Write
lock to the datanode.
In the current trunk, a RentrentLock is used, so it is always exclusive.
However there are many code paths in the DN where an exclusive lock is not
necessary and a read lock would suffice.
We know the Re
Hi All,
In https://issues.apache.org/jira/browse/HDFS-14854 we committed a new
decommission monitor to trunk, which is disabled by default. The new
implementation hopes to be an improvement over the original monitor, but
without running it on a real cluster it is hard to know for sure.
I would li
Are you seeing this problem on the 3.x branch, and if so, did the problem
exist before you upgraded to 3.x? I am wondering if the situation is better
or worse since moving to 3.x.
Also, do you believe the issue is driven by the namenode holding its lock
for too long while it processes each block r
Hi,
A long time back there was a Jira raised to change the default volume

https://issues.apache.org/jira/browse/HDFS-8538
At the time there were some objections / concerns about using available
space.
In the 5 years since then, at Cloudera we

Hi All,
I have a patch (HADOOP-14698) where the mvnsite step is failing with:
ERROR: yetus-dl: gpg unable to import

Hi All,
Sorry for being a bit late to this, but I wonder if we have a potential
blocker to this release.
In Cloudera we have recently encountered a serious dataloss issue in HDFS
surrounding snapshots. To hit the dataloss issue, you must have HDFS-13101
and HDFS-15012 on the build (which branch-3
Hi Gabor,
We recently discovered a HDFS data loss issue in any build which uses
snapshots containing HDFS-13101 but not including HDFS-15313. Unfortunately
3.1.4 falls into this category:
git log origin/branch-3.1.4 | egrep "HDFS-(15313|13101)"
HDFS-15012. NN fails to parse Edit logs after a

I agree with Owen on this - I don't think this is a feature we should add
to HDFS.
If managing the permissions for Hive tables is becoming a big overhead for
you, you should look into something like Sentry. It allows you to manage
the permissions of all the files and folders under Hive tables in a

I compiled a native build from source and started a non-HA, non-HA secure
(TLS and Kerberos) and a HA hdfs cluster using docker.
On each, I created a few files, looked around the webUI etc. Everything
looks fine. The only strange thing, was on the Namenode webUI under the
overview section - the "u
I have not tried to do this, but as we (Cloudera) deal with more and more
performance related problems, I feel something like this is needed.
It is a tricky problem due to the number of requests the NN handles and how
performance sensitive it is.
At the IPC Server level, we should be able to know
I am +1 on increasing the line length to 100.
As for changes to address existing style issues - I think that is more pain
than it's worth. It will make backports much harder, and we have quite a
few active branches, not to mention those who maintain custom builds.
