Re: Caused by: java.io.InterruptedIOException

Hey Raja, We'll need more details about your setup (HBase version, size/topology of cluster, server specs, etc.) and the applications you're running before we can even start giving ideas of things to try. Wanna pass those along? -Dima On Monday, July 11, 2016, Raja.Aravapalli

Re: Escaping separator in data while bulk loading using importtsv tool and ingesting numeric values

Hi Mahesha, 1.) HBase stores all values as byte arrays, so there's no typing to speak of. ImportTsv is simply ingesting what it sees, quotes included (or not). 2.) ImportTsv doesn't support escaping, if I'm reading the code correctly. (

Re: NoClassDefFoundError org/apache/hadoop/hbase/HBaseConfiguration

Hey Robert, HBaseConfiguration is part of the hbase-common module of the HBase project. Are you using Maven to provide dependencies or just running java -cp? -Dima On Monday, July 4, 2016, Robert James wrote: > When trying to load HBase via Spark, I get

Re: Delete row that has columns with future timestamp

Hey M., Just to follow up on what JMS said, this was fixed in April 2014 (details at https://issues.apache.org/jira/browse/HBASE-10118), so running a version of HBase in which the patch went in is probably your best option. -Dima On Sunday, June 26, 2016, Jean-Marc Spaggiari

Re: `hbase classpath` command causes “File name too long” error

You weren't setting the classpath. In Bash, you can't put a $ in front of the variable name when you're assigning it to a value. -Dima On Wednesday, June 22, 2016, Mahesha999 wrote: > hey thanks. That worked. Seems that my lack of experience with Linux > causing > trouble.

Re: Command to get HBase table owner

someone more seasoned than me can explain the justification… Things like replication_scope can be seen by using ‘describe' from the HBase shell. Other metadata (e.g. modified time) is not kept for HBase tables as far as I’m aware. -Dima On Wed, Jun 8, 2016 at 12:44 AM, Dima Spivak <dspi...@cloudera.

Re: Command to get HBase table owner

Hi Kumar, Which version of HBase do you run? Recent releases have moved to ACLs for table permissions in place of an "owner" construct. -Dima On Wednesday, June 8, 2016, kumar r wrote: > Hi, > > Is there any command to get complete description about hbase table such as >

FWIW, some engineers at Cloudera who worked on adding encryption at rest to HDFS wrote a blog post on this where they describe negligible performance impacts on write and only a slight performance degradation on large reads (
