Write 
The supported data types and corresponding conversion relationships for HBase writing are as follows (when processing HBase, the data type of the HBase data source and the data type of the data processing engine will be mapped first):
Internal Types
HBase Type
CHAR,VARCHAR,STRING
byte[] toBytes(String s),String toString(byte[] b)
BOOLEAN
byte[] toBytes(boolean b),boolean toBoolean(byte[] b)
BINARY VARBINARY
Returns byte[] as is.
DECIMAL
byte[] toBytes(BigDecimal v),BigDecimal toBigDecimal(byte[] b)
TINYINT
new byte[] { val },bytes[0] // returns first and only byte from bytes
SMALLINT
byte[] toBytes(short val),short toShort(byte[] bytes)
INT
byte[] toBytes(int val),int toInt(byte[] bytes)
BIGINT
byte[] toBytes(long val),long toLong(byte[] bytes)
FLOAT
byte[] toBytes(float val),float toFloat(byte[] bytes)
DOUBLE
byte[] toBytes(double val),double toDouble(byte[] bytes)
DATE
Stores the number of days since epoch as int value.
TIME
Stores the number of milliseconds of the day as int value.
TIMESTAMP
