Trending reports hangs in "looking for available data processor" state
The trending report generation is not able to use the Data Processor assigned in the Host pool.
The suggestions to resolve this issue are
a) Make sure there is enough disk space on the Data Processor machine
b) Clean the TEMP folder or move it to another drive
c) Free the Data Processor host from the pending collations or analysis task or any other invalid runs in which the Data Processor was earlier used as a host.
