> Ignite node fails to start if some , but not all 3 HADOOP_XXX_HOME variables are set (see trace below). This is caused by the following gap in Ignite logic: 
> {{org.apache.ignite.internal.processors.hadoop.HadoopClasspathUtils#exists , #isDirectory , #isReadable}} return {{true}} for empty String argument. For the unset location variables the value is empty String, but {{org.apache.ignite.internal.processors.hadoop.HadoopLocations#xxxxxExists}} gets {{true}}, so the location considered to be valid. This is the cause of the problem.
