Subject [jira] [Updated] (CASSANDRA-8351) Running COPY FROM in cqlsh aborts with errors or segmentation fault
Date Mon, 08 Dec 2014 20:29:12 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-8351?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mikhail Stepura updated CASSANDRA-8351:
---------------------------------------
    Description: 
Running Cassandra 2.1.2 binary tarball on a single instance.

Put together a script to try to reproduce this using data generated by cassandra-stress.

Reproduction steps: Download files and run cqlsh -f stress.cql
This may need to run a couple of times before errors are encountered. I've seen this work
best when running after a fresh install.

Errors seen:

1.    Segmentation fault (core dumped)

2.    
{code}
       stress.cql:24:line contains NULL byte
       stress.cql:24:Aborting import at record #0. Previously-inserted values still present.
       71 rows imported in 0.100 seconds.{code}

3.   
{code}*** glibc detected *** python: corrupted double-linked list: 0x0000000001121ad0 ***

  was:
Running Cassandra 2.1.2 binary tarball on a single instance.

Put together a script to try to reproduce this using data generated by cassandra-stress.

Reproduction steps: Download files and run cqlsh -f stress.cql
This may need to run a couple of times before errors are encountered. I've seen this work
best when running after a fresh install.

Errors seen:

1.    Segmentation fault (core dumped)

2.    stress.cql:24:line contains NULL byte
       stress.cql:24:Aborting import at record #0. Previously-inserted values still present.
       71 rows imported in 0.100 seconds.

3.   *** glibc detected *** python: corrupted double-linked list: 0x0000000001121ad0 ***

>            Reporter: Joseph Chu
>            Priority: Minor
>              Labels: cqlsh

> Running Cassandra 2.1.2 binary tarball on a single instance.
> Put together a script to try to reproduce this using data generated by cassandra-stress.
> Reproduction steps: Download files and run cqlsh -f stress.cql
> This may need to run a couple of times before errors are encountered. I've seen this
work best when running after a fresh install.
> Errors seen:
> 1.    Segmentation fault (core dumped)
> 2.    
> {code}
>        stress.cql:24:line contains NULL byte
