### Question:
HbaseSchemaUtils { public static String[] extractColumnParts(String glueColumnName) { return glueColumnName.split(NAMESPACE_QUALIFIER); } private  HbaseSchemaUtils(); static Schema inferSchema(HBaseConnection client, TableName tableName, int numToScan); static String getQualifiedTableName(TableName tableName); static org.apache.hadoop.hbase.TableName getQualifiedTable(TableName tableName); static Types.MinorType inferType(byte[] value); static Object coerceType(boolean isNative, ArrowType type, byte[] value); static String[] extractColumnParts(String glueColumnName); static byte[] toBytes(boolean isNative, Object value);  }### Answer:
@Test public void extractColumnParts() { String[] parts = HbaseSchemaUtils.extractColumnParts("family:column"); assertEquals("family", parts[0]); assertEquals("column", parts[1]); }
