Re: SSTableLoader Question

[Rahul Singh]

If you don’t have access to the file you don’t have access to the file. I’ve 
seen this issue several times. It’s he easiest low hanging fruit to resolve. So 
figure it out and make sure that it’s Cassandra.Cassandra from root to he Data 
folder and either run as root or sudo it.

If it’s compacted it won’t be there so you won’t have the file. I’m not aware 
of this event being communicated to Sstableloader via SEDA. Besides, the 
sstable that you are loading SHOULD not be live. If you at streaming a life 
sstable, it means you are using sstableloader not as it is designed to be used 
- which is with static files.

Re: SSTableLoader Question

[shalom sagges]

Not really sure with which user I ran it (root or cassandra), although I
don't understand why a permission issue will generate a File not Found
exception?

And in general, what if a file is being streamed and got compacted before
the streaming ended. Does Cassandra know how to handle this?

Thanks!

Check permissions maybe? Who owns the files vs. who is running sstableloader.

SSTableLoader Question

[shalom sagges]

Hi All,

C* version 2.0.14.

I was loading some data to another cluster using SSTableLoader. The
streaming failed with the following error:


Streaming error occurred

Did I miss something when running the load? Was the file suddenly missing
due to compaction?
If so, did I need to disable auto compaction or stop the service
beforehand? (didn't find any reference to compaction in the docs)

I know it's an old version, but I didn't find any related bugs on "File not
found" exceptions.

Thanks!

Re: [Marketing Mail] Re: [Marketing Mail] Re: sstableloader question

[Osman YOZGATLIOGLU]

Hello,

It's about 2500 sstables worth 25TB of data.
-t parameter doesn't change -t 1000 and -t 1
Most probably I face some limitation at target cluster.
I'm preparing to split sstables and run up to ten parallel sstableloader 
sessions.

Osman

But each job runs about 10MB/sec only and generates about 100Mbit'sec network

Hi Osman,

You cannot restart the streaming only to the failed nodes specifically. You
can restart the sstableloader job itself. Compaction will eventually take
care of the redundant rows.

sstableloader question

[Osman YOZGATLIOGLU]

Hello,

I have running a sstableloader job.
Unfortunately some of nodes restarted since beginnig streaming.
I see streaming stop for those nodes.
Can I restart those streaming somehow?
Or if I restart sstableloader job, will it start from beginning?

Regards,
Osman
