I am having 3 node cluster with replication factor 2 and one of my Cassandra node was down and I started receiving following exception in my java service in

So my guess is that your SYSTEM_AUTH keyspace has a RF=1 and the node that went down had your authentication record (user row). You could try a different user who's data resided on an available host to get connected, and drop/recreate the affected users, etc. In general, ensure that the SYSTEM_AUTH table is replicated to something higher than 1 (with 3 nodes, I would simply change it to 3, but you could do 2 and hopefully be safe for a single node failure).

I have a 9 node Cassandra (version 3.7) cluster which are under heavy load always. Many of the nodes goes down frequently one after another or some time simultaneously.
On few of the nodes, even Cassandra is showing up, but nodetool status is throwing error as NullPointerException.
Below is the log:
ubuntu#ip-##:~$ nodetool status
error: null

It is not letting the service UP and I have no clue of where to look into.
We were badly running in a serious issue and it was on Production, so we eventually spawn a new Cluster and Shuts it down. I will close the issue and reopen a new thread if we come across the same issue

I am deploying my application on yarn (cluster mode) using Spark 1.6 and Mapr 5.2 version.
As mentioned in the comments, the answer was already found here.
The answer is fortunately very straightforward:
It seemed like this was caused due to hadoop running out of disc space.
Obvious resolutions being an increase in diskspace or reduction in disk space usage.
I have Cassandra installed in multi node cluster, logically separated in 2 data centers as,
BC1 - Analytics applications are running on these nodes
BC2 - UI applications are running on these nodes
I have a keyspace created as,
CREATE KEYSPACE ks23 WITH replication = {
'class': 'NetworkTopologyStrategy', 'BC2': '3'
};
When I try to access the table data from above keyspace using pig script which is running on one of the BC1 node, I get this error,

I got the following exception when i was trying to decommission a live node. There is no reference in the manual saying that i need to stop the data coming into this node. Even then, decommissioning is specified for live nodes.
Can anyone let me know if am doing something wrong or if this is a bug on cassandra part?

I'm currently in the middle of migrating 4.8 billion rows from MySQL which I do via sstableloader in batches of 1 to 4 million rows. Does the exception mean that I've already lost data and must repeat the migration from scratch? So far I don't see any stream error in my logs.
My environment is as follows:
DSE 4.0.1 (Cassandra 2.0.5)
CentOS 6.x x86_64
Java 1.7.0_5x
EDIT:
Some additional info:
During the bulk loading process, I devised a mechanism to kill the sstableloader when the total progress reaches 100%. I also issue a "nodetool stop INDEX_BUILD" to all nodes. The reason for this is because sstableloader waits for the secondary index build to finish and this takes hours to complete (whereas the actual import time is just a fraction of the index build time). I figured out that the imported data remains intact after killing the sstableloader process and cancelling the secondary index build so I wrote a script to automate the mechanism. So far, I have completed more than 200 bulk loads with this trick.
I have paused the migration and restarted the nodes several times in the past week because the OS load reaches high levels (yellow or red in OpsCenter) after finishing several cycles of note #1. It's possible that a compaction is in progress when I restarted the nodes via dse cassandra-stop (yes, we are running DSE as a standalone process)
Could any of these be the cause? How do I get out of this situation? Manual compaction/repair doesn't work because they always throw exceptions. For repair, the exception is different but the meaning is the same - some sstable files are missing:

Have you dropped and recreated the keyspace? If so, it's probably this:
https://issues.apache.org/jira/browse/CASSANDRA-4857
Restart your nodes to clear the bad filename out of memory.
