Upgrade from Hbase 0.94.6 to 0.96 (From CDH45. - CDH 5.0)

Hi, I am trying to upgrade from CDH4.5 (which contains Hbase 0.94.6) to CDH5.0 (which contains hbase 0.96). From Cloudera documentation I found that: Rolling upgrades from CDH 4 to CDH 5 are not possible because existing CDH 4 HBase clients cannot make requests to CDH 5 servers and CDH 5 HBase

Re: Upgrade from Hbase 0.94.6 to 0.96 (From CDH45. - CDH 5.0)

Hortonworks has written a bridge tool to help with this. As far as I know, this will only work for replicating from a 0.94 cluster to a 0.96 cluster. Check out https://github.com/hortonworks/HBaseReplicationBridgeServer On Mon, Jun 2, 2014 at 7:35 AM, yanivG yaniv.yancov...@gmail.com wrote:

hbase block-cache scan.setCaching(false) not being respected

Hi all, We are running a number of Map/Reduce jobs on top of HBase. We are not using HBase for any of its realtime capabilities, only for batch-processing. So we aren't doing lookups, just scans. Each one of our jobs has *scan.setCaching(false)* to turn off block-caching, since each block will

Re: hbase block-cache scan.setCaching(false) not being respected

The Block Cache is used for more than just the scanner caching. Additionally, *hfile.block.cache.size *is a server-side config, while scan.setCaching(false) is on an RPC-level. So regardless of your setCaching value the RegionServers will continue to allocate memory to the block cache. Check

Re: hbase block-cache scan.setCaching(false) not being respected

Have you added the following when passing Scan to your job ? scan.setCacheBlocks(false); BTW image didn't go through. Consider putting image on third-party site. On Mon, Jun 2, 2014 at 12:55 PM, Matt K matvey1...@gmail.com wrote: Hi all, We are running a number of Map/Reduce jobs on top of

HBase REST using ssl

hi, folks, I am wondering how to use ssl with HBase REST, and look at http://wiki.apache.org/hadoop/Hbase/Stargate, and google a bit. but couldn't find examples or instructions. Can someone give me a couple pointers? thanks Demai

Re: HBase REST using ssl

Hi Demai, You need to set these configurations for your REST server: hbase.rest.ssl.enabled hbase.rest.ssl.keystore.store hbase.rest.ssl.keystore.password hbase.rest.ssl.keystore.keypassword Thanks, Jimmy On Mon, Jun 2, 2014 at 3:23 PM, Demai Ni nid...@gmail.com wrote: hi, folks, I am

Hi, thanks for responses. Ted - when I said scan.setCaching, I meant scan.setCacheBlocks(false). That's what I get for not copying/pasting directly from code :) I added a link to the graphs here: https://drive.google.com/file/d/0B3ZQ0nMNMFxCOHZNZVFsWEhCOUU/edit?usp=sharing Bryan - I believe
