David Wayne Birdsall updated TRAFODION-2728: -------------------------------------------- Description: When doing a SHOWSTATS on a native HBase table, the error message is strange if the <code>"_HBASESTATS_"</code> histogram tables do not exist. For example, in a fresh instance where that schema has not been created yet: >>showstats for table hbase."_ROW_"."xyz" on existing columns; >> *** ERROR[9200] UPDATE STATISTICS for table HBASE._ROW_.xyz encountered an error (4082) from statement . *** ERROR[4082] Object TRAFODION."_HBASESTATS_".SB_HISTOGRAMS does not exist or is inaccessible. *** ERROR[8822] The statement was not prepared. --- SQL operation failed with errors. However, if the "_HBASESTATS_" schema and histogram tables exist, we get a more friendly and normal looking error: >>showstats for table hbase."_CELL_"."xyz" on existing columns; Histogram data for Table HBASE."_CELL_"."xyz" Table ID: 0 Hist ID # Ints Rowcount UEC Colname(s) ========== ====== =========== =========== =========================== No Histograms exist for the requested columns or groups --- SQL operation complete. >> The objective of this JIRA is to give the latter error message even if the "_HBASESTATS_" histograms tables do not exist. was: When doing a SHOWSTATS on a native HBase table, the error message is strange if the "_HBASESTATS_" histogram tables do not exist.
