I wonder; your jar creation looks a little off and I suspect your problem might be the jar format which would lead to the failure to load. Could you list the output of $ unzip -l my.jar? On Jul 28, 2014 3:49 AM, "Martin Marinov" wrote: > I did: > ls /etc/cassandra/triggers/ > InvertedIndex.jar

Re: Cassandra trigger following the CQL for Cassandra 2.0 tutorial does not work

This is not really a Cassandra problem: it's a basic Java packaging problem. First of all, the java source file is not what the runtime needs to see in your jar; it needs the class file which was generated by compiling it. That compiled class needs to be in a folder corresponding to it's package,

Re: Cassandra trigger following the CQL for Cassandra 2.0 tutorial does not work

How to compile is a much biggest question and probably way off topic for this list. I think you need a starter tutorial on building and packaing java; there is more than one concept at work. you will need a compiler of the appropriate version. that source has external dependancies declared in th

Re: Cassandra trigger following the CQL for Cassandra 2.0 tutorial does not work

To be clear, Cassandra triggers require that you be a skilled and confident Java developer. If you aren't fluent in Java and the Java development process, triggers are not a great place to start learning Java. That said, maybe the doc does need to be a little more clear about some of the speci

Thrift vs CQL3 performance

Hi every one, I'm newcomer to Cassandra, so I would like to know about performance between Thrift (Hector) vs CQL3, specially about the speed (Thrift based on RPC, CQL3 based on binary protocol). Currently I'm using Cassandra 1.2 , which version CQL3 of JavaDriver-Datastax is stable for it?

Re: Full GC in cassandra

1) Is that heap dump after full GC? 2) Are you doing a lot of concurrent writes to the same partition 3) Is the system hinting at the time of the spike 4) when you say “spike” do you mean this is unusually high? On Jul 28, 2014, at 11:07 AM, Keith Wright wrote: > What’s your cfhistograms look li

cassandra [2.1.0-rc4] does not filter data out when using WHERE clause on cluster column

Hi everyone, I have a weird, invalid situation with my cluster. I have a table on which I'm running some SELECTs with WHERE clause filtering on cluster columns, but the rows are not getting filtered out. Look: select * from page_view where website_id = xxx and user_id = 'some_user' and page_id =0;

Have you created the schema for these data files? I meant the schema should be created before you load these data file to C*. Here is the article for introduction of sstableloader that you could refer. http://www.datastax.com/documentation/cassandra/1.2/cassandra/tools/toolsBulkloader_t.html On

Settings for "old" tables to optimize storage space

After much help from this list, I've moved to a date-based table schema. Once a date has passed, there will be very little, if any, writing to that table. As such, I have a nightly process that goes through a performs a major compaction to move it down to a single table. I've tried manipulating t
