Wei-Chiu Chuang commented on HDFS-15315:
----------------------------------------
Thanks
At Cloudera we did not test EC with Solr so this is possible. It's not
explicitly written in the Cloudera's user doc though:
[https://docs.cloudera.com/runtime/7.1.0/scaling-namespaces/topics/hdfs-ec-overview.html]
{quote}EC supports the following data processing engines:
* Hive
* MapReduce
* Spark

> Key: HDFS-15315
> URL: https://issues.apache.org/jira/browse/HDFS-15315
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: 3.1.1, hdfs
> Affects Versions: 3.1.1
> Environment: XOR-2-1-1024k policy on hadoop 3.1.1 with 3 datanodes
> Reporter: Anshuman Singh
> Priority: Major
>
> When using Erasure Coding policy on a directory, the replication factor is
> set to 1. Solr fails in indexing documents with error - _java.io.IOException:
> Unable to close file because the last block does not have enough number of
> replicas._ It works fine without EC (with replication factor as 3.) It seems
> to be identical to this issue. [
