This example shows how to build and run a Maven-based project to execute SQL queries on Impala using JDBC. Therefore, before shifting the bits the decimal value of a is 240, and after shifting the bits the decimal value of a is 60. Impala-shell. Before you start with this tutorial, we expect you to have an existing Apache Kudu instance with Impala installed. JDBC connectivity with Impala for SQuirreL. Let's use the bitwise inclusive OR operator in a Java program. The value of a is -10. It is a binary operator denoted by the symbol | (pronounced as a pipe). It returns 1 if either of the bit is 1, else returns 0. In the above example, we have observed that after shifting the operator 256 converted into 16 and -256 converted into -16. In the above example, a===b will return true, because the value of a and b is 5 and both are number data types, a===c will return false because the value of a and c is 5, but the data types are different. It returns 0 if both bits are the same, else returns 1. It is a binary operator denoted by the symbol ^ (pronounced as caret). ###Cloudera Impala JDBC Example.
