Question about "No registered leader" error

Hi all I got an error when I was doing index operation: "2019-09-18 02:35:44.427244 ... No registered leader was found after waiting for 4000ms , collection: foo slice: shard2" Beside it, there is no other error in solr log. Collection foo have 2 shards, then I check their jvm gc log: *

Re: Why I receive permission denied when running as root

What it looks like is that execute permissions aren't set on bin/solr, have you checked that? Best, Erick On Tue, Sep 17, 2019 at 10:40 AM Shawn Heisey wrote: > > On 9/16/2019 9:06 PM, Raymond Xie wrote: > > [root@pocnnr1n1 solr]# bin/solr start > > -bash: bin/solr: Permission denied > > The

Re: Why I receive permission denied when running as root

Thank you Paras: If I am already user of root, and still run sudo? no, it doesn't work: [root@pocnnr1n1 solr]# sudo bin/solr start -force sudo: bin/solr: command not found [root@pocnnr1n1 solr]# ls -l bin/solr -rw-r--r-- 1 root root 80630 Jul 19 09:09 bin/solr So, I followed your suggestion and

Re: Why I receive permission denied when running as root

Hey Raymond, bin/solr start -force I know this could be useless, but did you try the following (notice the sudo)? *sudo* bin/solr start -force Also, I suggest you to review permission of solr file by: ls -l bin/solr If you don't see required executable permissions, you can provide root

Re: Why I receive permission denied when running as root

Maybe the execute permission is missing on bin/solr? Try `chmod a+x bin/solr` (this gives *all* users execute permission for bin/solr). On 17.09.19 14:33, Raymond Xie wrote: > Thank you. > > As I suspected, this is something else. It prompts me the same error here: > [root@pocnnr1n1 solr]#

Re: Why I receive permission denied when running as root

Thank you. As I suspected, this is something else. It prompts me the same error here: [root@pocnnr1n1 solr]# bin/solr start -force -bash: bin/solr: Permission denied [root@pocnnr1n1 solr]# It is not a good practice to use root directly, however, using root should not have permission error. This

Re: HDFS Shard Split

SplitShardCmd assumes that its main phase (when the Lucene index is being split) always executes on the local file system of the shard leader, and indeed the ShardSplitCmd.checkDiskSpace() checks the local file system’s free disk space - even though in reality in your case the actual data is

Re: Is shard split operation multithreaded?

If I understand your question correctly .. it’s single-threaded with regard to a specific shard - but you can run multiple shard splitting operations in parallel IFF they affect different shards (or different collections). See SplitShardCmd for the details of locking and how the new sub-shards

Is shard split operation multithreaded?
