Attachment: sstable-histogrambuster.tar.bz2
8028-2.1-clean.txt
I've attached a rebased patch, and the sstable that I used to make sure that
the overflow was fixed.
The schema is:
{noformat}
CREATE TABLE sstable.histogrambuster (name text, id bigint, PRIMARY KEY (name,
id))
{noformat}

[ https://issues.apache.org/jira/browse/CASSANDRA-8028?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Carl Yeksigian updated CASSANDRA-8028: -- Attachment: 8028-trunk.txt Good catch, [~Cameron Hatfield]. I don't know how I missed that before. :) This will still be a breaking change which should wait until 3.0. nodetool currently expects the size of the buckets to always be 90, and will fail an assertion if we make changes on the server to send the full histogram to the client. I've attached a patch against trunk that does send the full histogram as it is persisted. > Unable to compute when histogram overflowed > --- > > Key: CASSANDRA-8028 > URL: https://issues.apache.org/jira/browse/CASSANDRA-8028 > Project: Cassandra > Issue Type: Bug > Components: Tools > Environment: Linux >Reporter: Gianluca Borello >Assignee: Carl Yeksigian > Fix For: 2.1.2 > > Attachments: 8028-2.1.txt, 8028-trunk.txt > > > It seems like with 2.1.0 histograms can't be computed most of the times: > $ nodetool cfhistograms draios top_files_by_agent1 > nodetool: Unable to compute when histogram overflowed > See 'nodetool help' or 'nodetool help '. > I can probably find a way to attach a .cql script to reproduce it, but I > suspect it must be obvious to replicate it as it happens on more than 50% of > my column families. -- This message was sent by Atlassian JIRA (v6.3.4#6332)

There are probably very large partitions which are overflowing our histogram. In order to get around this, we'll need to increase the amount of data that is persisted and break compatibility of nodetool, so it will have to wait for 3.0. I have attached a check so that the other information can be gathered, except for the metric that has overflowed. > Unable to compute when histogram overflowed > --- > > Key: CASSANDRA-8028 > URL: https://issues.apache.org/jira/browse/CASSANDRA-8028 > Project: Cassandra > Issue Type: Bug > Components: Tools > Environment: Linux >Reporter: Gianluca Borello >Assignee: Carl Yeksigian > Attachments: 8028-2.1.txt > > > It seems like with 2.1.0 histograms can't be computed most of the times: > $ nodetool cfhistograms draios top_files_by_agent1 > nodetool: Unable to compute when histogram overflowed > See 'nodetool help' or 'nodetool help '. > I can probably find a way to attach a .cql script to reproduce it, but I > suspect it must be obvious to replicate it as it happens on more than 50% of > my column families. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
