Hi,

hmm,

the Apache Hadoop installation may not have a value for theyarn.application。classpathproperty, which is then treated as a default value according tohttps://hadoop.apache.org/docs/r2.6.2/hadoop-yarn/hadoop-yarn-common/yarn-default.xml.

I would try to add a new Advanced Hadoop Parameter entry with key=yarn.application。classpathand empty value. You may get a warning when closing the dialog that the value is empty, but that can be ignored in this case (according to the yarn defaults, empty means default). If this does not work, the multi-line default value that is described in the link above for this property can be copy-pasted to the value cell instead.

Best,

Peter

Hi,

those links only point to the default address of these pages, they may run at different ports. These addresses are actually not used by RapidMiner.

However, I suspect that in this case, the opening of the default browser fails. Can you open these addresses in Mozilla? If not, the ports may be different.

This should not affect anything else in RapidMiner.

Best,

Peter
