I've seen this before in jruby, but I can't recall the fix. Maybe try the JRuby list if nobody knows? On Wednesday, December 2, 2015, Josh Harrison wrote: > Thanks for your help Samarth, unfortunately I’ve still got the same error > after these steps, to give the full error: > > NameError: canno

Re: JRuby on rails -> Phoenix connection error - cannot load java class

Thanks for your help Samarth, unfortunately I’ve still got the same error after these steps, to give the full error: NameError: cannot link Java class org.apache.phoenix.jdbc.PhoenixDriver, probable missing dependency: Could not initialize class org.apache.phoenix.jdbc.PhoenixDriver

Re: JRuby on rails -> Phoenix connection error - cannot load java class

Josh, One step worth trying would be is to register the PhoenixDriver instance and see if that helps. Something like this: DriverManager.registerDriver(PhoenixDriver.INSTANCE) Connection con = DriverManager.getConnection("jdbc:phoenix:localhost:2181”) - Samarth On Wed, Dec 2, 2015 at 3:41 PM,

Re: JRuby on rails -> Phoenix connection error - cannot load java class

Thanks for your help and quick response Russell. This does seemed to have progressed things, however I’m now getting the following error: NameError: cannot link Java class org.apache.phoenix.jdbc.PhoenixDriver, probable missing dependency: Could not initialize class org.apache.phoenix.jdbc.Pho

Re: spark plugin with java

It does. Under the hood, the DataFrame/RDD makes use of the PhoenixInputFormat, which derives the split information from the query planner and passes those back through to Spark to use for its parallelization. After you have the RDD / DataFrame handle, you're also free to use Spark's repartition()

Re: spark plugin with java

Yes, I will create new tickets for any issues that I may run into. Another question: For now I'm pursuing the option of creating a dataframe as shown in my previous email. How does spark handle parallelization in this case? Does it use phoenix metadata on splits? On Wed, Dec 2, 2015 at 11:02 AM,

Re: JRuby on rails -> Phoenix connection error - cannot load java class

This seems like a class path problem. Try specifying the class path to the jar with that class in it via: CLASSPATH=/foo/bar.jar jruby ... On Wednesday, December 2, 2015, Josh Harrison wrote: > Hi Guys, > > We’re trying to spin up a testing version of Phoenix and integrate it with > a Jruby on r

JRuby on rails -> Phoenix connection error - cannot load java class

Hi Guys, We’re trying to spin up a testing version of Phoenix and integrate it with a Jruby on rails application. I have Phoenix and Hbase successfully installed, configured and talking to each other, but am coming up with a ‘cannot load java class’ error when trying to make the connection to

Re: spark plugin with java

Hi Krishna, That's great to hear. You're right, the plugin itself should be backwards compatible to Spark 1.3.1 and should be for any version of Phoenix past 4.4.0, though I can't guarantee that to be the case forever. As well, I don't know how much usage there is across the board using the Java A

Re: Phoenix(+Query Server) with Namenode HA

Are you sure your HA configuration is working properly, I doubt this is related to Phoenix. Are these parameters correctly setup? hbase-site.xml hbase.rootdir hdfs://nameservice/hbase hdfs-site.xml dfs.nameservices nameservice dfs.ha.namenodes.nameservice nn

Re: spark plugin with java

Yes, that works for Spark 1.4.x. Website says Spark 1.3.1+ for Spark plugin, is that accurate? For Spark 1.3.1, I created a dataframe as follows (could not use the plugin): *Map options = new HashMap();* *options.put("url", PhoenixRuntime.JDBC_PROTOCOL + PhoenixRuntime.JDBC_PROTOCO

Custom Aggregator Functions

Hi guys, We're planning to upgrade Phoenix 4.2.0 to Phoenix 4.4. As part of this process, we'll need to migrate our custom UDFs, with the new feature provided by 4.4. However, the documentation only describes how to create an Scalar function, not an aggregator one. Are User Defined Aggregator Fun
