Subject Re: OutOfMemoryError with Hadoop backing filesystem
Date Mon, 09 Nov 2015 09:08:13 GMT

Since IGFS is used as a secondary file system for Hadoop you can enable
eviction policy for IGFS.

IgfsPerBlockLruEvictionPolicy has two parameters - maxSize and maxBlocks.
When any parameter exceeds the policy will evict last recently used data
from the memory. When previously evicted data is requested it will be loaded
from Hadoop to the memory automatically. 

The eviction policy with default parameters can be added this way to your

<bean id="dataCacheCfgBase"
class="org.apache.ignite.configuration.CacheConfiguration" abstract="true">
<property name="evictionPolicy"
