Confirming a Bug

Hello, A couple of days ago, I asked about strange behavior in my "Scan.addFamiliy reduces results" thread. I want to confirm that I did find a bug, and if so, how to submit a bug report. The basic strangeness is that changing the amount of caching, changes the number of results. In the o

Hi, Harsh. Thank you for your reply and I understand. I don't think it's so important right now, but if I think so, I'll file a JIRA. Anyway, thank you very much! 2012/3/17 Harsh J > No, "Über" jars are not supported. The jar is merely injected onto the > classpath directly. > > Please file a

Re: Using external libraries in Coprocessor

No, "Über" jars are not supported. The jar is merely injected onto the classpath directly. Please file a JIRA if you consider it important that HBase coprocessor hosts support Über jar loading. For the meanwhile, just create exploded library jars, with all class files residing in the root, and not

Re: Using external libraries in Coprocessor

You need to follow the second approach ("Load from table attribute") to specify a jar path along with your coprocessor classes: http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/coprocessor/package-summary.html#load - Your single jar should contain all required dependencies. Otherwise, just

How can I see the right format data content when I export the table content from Hbase?

Hello, I have used the command ./hbase org.apache.hadoop.hbase.mapreduce.Export 'test' http://localhost:8020/test to export the data content from the test table. And I can see the exported content from my hdfs folder, hdfs://localhost/test/part-m-0. I have tried 2 commands to read the content

Using external libraries in Coprocessor

Hi all, Is there any way for Coprocessors to use external libraries? Hadoop MapReduce can specify them by using -libjars command line arguments or including 'lib' directory in job.jar file. I also want to use external libraries in Coprocessors. Thanks. -- Takuya UESHIN Tokyo, Japan http://tw
