Hi all, I am using Phoenix version 4.5.0 and the phoenix-spark plugin to write into HBase an ARRAY of UNSIGNED_SMALLINT. As stated in the documentation, this type is mapped to the java type java.lang.Short.
Using the saveToPhoenix method on a RDD and passing a Scala Array of Short I obtain the following stacktrace: Caused by: java.lang.ClassCastException: *[S cannot be cast to [Ljava.lang.Object;* at org.apache.phoenix.schema.types.PUnsignedSmallintArray.isCoercibleTo(PUnsignedSmallintArray.java:81) at org.apache.phoenix.expression.LiteralExpression.newConstant(LiteralExpression.java:174) at org.apache.phoenix.expression.LiteralExpression.newConstant(LiteralExpression.java:157) at org.apache.phoenix.expression.LiteralExpression.newConstant(LiteralExpression.java:144) at org.apache.phoenix.compile.UpsertCompiler$UpsertValuesCompiler.visit(UpsertCompiler.java:872) at org.apache.phoenix.compile.UpsertCompiler$UpsertValuesCompiler.visit(UpsertCompiler.java:856) at org.apache.phoenix.parse.BindParseNode.accept(BindParseNode.java:47) at org.apache.phoenix.compile.UpsertCompiler.compile(UpsertCompiler.java:745) at org.apache.phoenix.jdbc.PhoenixStatement$ExecutableUpsertStatement.compilePlan(PhoenixStatement.java:550) at org.apache.phoenix.jdbc.PhoenixStatement$ExecutableUpsertStatement.compilePlan(PhoenixStatement.java:538) at org.apache.phoenix.jdbc.PhoenixStatement$2.call(PhoenixStatement.java:318) at org.apache.phoenix.jdbc.PhoenixStatement$2.call(PhoenixStatement.java:311) at org.apache.phoenix.call.CallRunner.run(CallRunner.java:53) at org.apache.phoenix.jdbc.PhoenixStatement.executeMutation(PhoenixStatement.java:309) at org.apache.phoenix.jdbc.PhoenixStatement.execute(PhoenixStatement.java:239) at org.apache.phoenix.jdbc.PhoenixPreparedStatement.execute(PhoenixPreparedStatement.java:173) at org.apache.phoenix.jdbc.PhoenixStatement.executeBatch(PhoenixStatement.java:1315) Changing the type of the column to CHAR(1) ARRAY and use an Array of String, the write operation succeds. What am I doing wrong? Thanks a lot, Riccardo --
