RadoopProxyfeature is not yet compatible withHDP3
Rounding errors may be observed after 6th digit with 'integer' arithmetic's which are limited toDECIMAL(9,6)precision inHiveServer2 3.0. Recommendation is to use 'real' instead for calculations which require higher precision.
Apply Model does not acceptDECIMALcolumns in input (same for previous versions, butHiveServer2 3.0introduces lot of implicit DECIMAL casts), which results in UDFArgumentTypeExceptions. The workaround is to cast 'integer' values to 'real' withType Conversionoperator.
Password based Kerberos authenticationis no longer supported because of incompatibilities with key renewals andHDP3configuration. Recommendation is to usekeytab based Kerberos authenticationinstead.
