Subject Encountering IllegalStateException while querying Phoenix
Date Wed, 19 Sep 2018 21:15:04 GMT
Hi there,

I have encountered the following exception while trying to query from
Phoenix (was able to generate the exception doing a simple SELECT
count(1)). I have verified (MD5) that each region server has the correct
phoenix jars. Would appreciate any guidance on how to proceed further in
troubleshooting this (or what could've caused this). Thank you!

java.lang.IllegalStateException: Expected single, aggregated KeyValue from
coprocessor, but instead received
keyvalues={\x03\x80\x00\x00\x00\x00\x8D\xB8Y\x80\x00\x00\x00\x01c$\xE7\x00\x04\x80\x00\x00\x00\x01\x0C\x95N\x80\x00\x00\x00\x01\xCCU\xF1/SL:_0/1525817954352/Put/vlen=1/seqid=0/value=x}

. Ensure aggregating coprocessors are loaded correctly on server
