ฉันพยายามโหลด MySQL tableLab5 ไปยัง Hive โดยใช้ Sqoop Sqoop วิ่งได้สำเร็จและนำข้อมูลจาก mysql ไปสู่ hdfs แต่การโยนข้อผิดพลาดตัวหนาด้านล่างเกี่ยวกับการHIVE_CONF_DIRไม่ได้ตั้งค่า ฉันได้ตั้งค่าHIVE_CONF_DIRใน~/.bashrcและ~/.profileเป็น:
export HIVE_HOME=/usr/local/hive
export HIVE_CONF_DIR=$HIVE_HOME/conf
ทั้งๆที่ฉันกำลังเผชิญกับHIVE_CONF_DIRข้อผิดพลาดด้านล่าง คุณกรุณาช่วยฉันด้วยข้อผิดพลาดนี้โดยเร็ว?

Mon Jul 16 13:27:38 IST 2018 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.
