Subject How to Reduce Block Size in Solr 6.3.0 Running on HDFS
Date Thu, 11 May 2017 08:56:46 GMT

Hi,

Having small files, I set the HDFS block size to 16m in hdfs-site.xml:

  <name>dfs.blocksize</name>
  <value>16m</value>

After restarting the HDFS daemons and the Solr cloud, the block size is
still 128 MB for new files.
Can this be due to the block cache slab size which is 128 MB in size?
How can the HDFS block size be reduced?

Thanks,
Sabine
