Greg Solovyev updated KUDU-3152: -------------------------------- Component/s: java client > KuduPredicate class in Java client does not handle Date columns > --------------------------------------------------------------- > > Key: KUDU-3152 > URL: https://issues.apache.org/jira/browse/KUDU-3152 > Project: Kudu > Issue Type: Bug > Components: client, java > Reporter: Greg Solovyev > Assignee: Greg Solovyev > Priority: Major > > I ran into this trying to add a Date type field to > nifi-kudu-controller-service > (https://issues.apache.org/jira/browse/NIFI-7551). The following code throws > _java.lang.IllegalArgumentException_ if _sql_date_ column is defined as DATE > and _value_ is either _java.sql.Date_ or _int_ > {code:java} > KuduPredicate.newComparisonPredicate(tableSchema.getColumn("sql_date"), > KuduPredicate.ComparisonOp.EQUAL, value){code} > If _value_ is DATE, _IllegalArgumentException_ is thrown by this code in > KuduPredicate class: > static long minIntValue(Type type) { > switch (type) { > case INT8: > return Byte.MIN_VALUE; > case INT16: > return Short.MIN_VALUE; > case INT32: > return Integer.MIN_VALUE; > case UNIXTIME_MICROS: > case INT64: > return Long.MIN_VALUE; > default: > throw new IllegalArgumentException("type must be an integer type"); > } > } > if _value_ is an integer, then _IllegalArgumentException_ is thrown by this > code > {code:java} > public static KuduPredicate newComparisonPredicate(ColumnSchema column, > ComparisonOp op, > long value) { > checkColumn(column, Type.INT8, Type.INT16, Type.INT32, Type.INT64, > Type.UNIXTIME_MICROS, > Type.DATE); > {code} > as a result, if you have a table with DATE column, you cannot scan for it > using the java client. > -- This message was sent by Atlassian Jira (v8.3.4#803005)
