Resolution: Duplicate
> cfhistograms doesn't work for some CFs
> --------------------------------------
>
> Key: CASSANDRA-8174
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8174
> Project: Cassandra
> Issue Type: Bug
> Environment: Cassandra 2.1 | Linux XXX 3.2.0-4-amd64 #1 SMP Debian
> 3.2.60-1+deb7u3 x86_64 GNU/Linux | java version "1.7.0_51"
> Reporter: Michał Jaszczyk
>
> After I upgraded cassandra to the latest version (2.0 -> 2.1), the nodetool
> cfhistograms doesn't work anymore. It doesn't work for most of my CFs but not
> for all of them, I cannot find the rule.
> Details for one CF:
> {code}
> $ ./nodetool -h isu cfhistograms yyy xxx
> nodetool: Unable to compute when histogram overflowed
> See 'nodetool help' or 'nodetool help <command>'.
> {code}
> I have just created new CF and started inserting some data. The cfhistograms
> doesn't work for this table as well.
> Example for different random CF which is similar to the one above:
> {code}
> $ ./nodetool cfhistograms yyy xxy
> yyy/xxy histograms
> Percentile SSTables Write Latency Read Latency Partition Size
> Cell Count
> (micros) (micros) (bytes)
