Re: Solr with HDFS configuration example running in production/dev

[Gézapeti]

Cloudera's default configuration for the HDFSDirectoryFactory

is very similar to yours in solrconfig.xml.  The solr.hdfs.home property is
provided as a java property during Solr startup and we haven't seen the ":"
issue yet.

Hope it helps

Re: Solr with HDFS configuration example running in production/dev

[Prashant Jyoti]

Hi Joe,
Yes I had made these changes for getting HDFS to work with Solr. Below are
config changes which I carried out:

 Changes in solr.in.cmd


set SOLR_OPTS=%SOLR_OPTS% -Dsolr.directoryFactory=HdfsDirectoryFactory
set SOLR_OPTS=%SOLR_OPTS% -Dsolr.lock.type=hdfs
set SOLR_OPTS=%SOLR_OPTS% -Dsolr.hdfs.home=hdfs://
hn1-pjhado.tvbhpqtgh3judk1e5ihrx2k21d.tx.internal.cloudapp.net:8020/user/solr-data


 Changes in solrconfig.xml



  hdfs://
hn1-pjhado.tvbhpqtgh3judk1e5ihrx2k21d.tx.internal.cloudapp.net:8020/user/solr-data

  /etc/hadoop/conf
  true
  1
  true
  16384
  true
  true
  16
  192


Let me know if you have any comments?

Thanks!

Re: Solr with HDFS configuration example running in production/dev

[Joe Obernberger]

Are you running with solr.lock.type=hdfs
?

Have you defined your DirectoryFactory - something like:


    true
    true
    43
    name="solr.hdfs.blockcache.direct.memory.allocation">true

    16384
    true
    true
    128
    1024
    hdfs://nameservice1:8020/solr8.2.0
    /etc/hadoop/conf.cloudera.hdfs1

HDFS will still be there, just NOT on the core package, but as a plug-in or 
contrib.

We have seen The : issue with hdfs With hbase and it won’t allow any IO if
hdfs sees a : in a path.   We found this with a storage array that uses
snapshots and had dates and times in a path with a :

I assume this is the exact same problem we have seen with HD FS. The :
character does not need to be within the path where data is being written
it’s anywhere it’s visible to HD FS

I suggest you start looking on your target storage device looking for any
path anywhere that’s visible to the index that has a :

BTW thank you for your exception stack trace, I am now reading about

Re: Solr with HDFS configuration example running in production/dev

[Andy Hind]

Hi

I would not go down this road. What is the use case?  Is this really the 
solution?

Go read all the relevant docs and configuration provided by 
Cloudera/HortonWorks and everything else related to SOLR and HDFS.

I am not inclined to help you down a road you do not want to travel. There be 
dragons!

Solr with HDFS configuration example running in production/dev

[Prashant Jyoti]

Hi all,
Hope you are healthy and safe.

Need some help with HDFS configuration.

Could anybody of you share an example of the configuration with which you
are running Solr with HDFS in any of your production/dev environments?
I am interested in the parts of SolrConfig.xml / Solr.in.cmd/sh which you
may have modified. Obviously with the security parts obfuscated.

I am stuck at an error and unable to move ahead. Attaching the exception
log if anyone is interested to look at the error.
