Running this code, I am trying to export a csv but I get the following error:
ParseException line 2:3 cannot recognize input near 'MIN' '(' 'HIGH' in expression specification
Try to add table alias (d) and use select d.* instead of select *:
hive -e "SELECT d.*,
MIN(HIGH) OVER(PARTITION BY SYMBOL ORDER BY TIMESTAMP) AS MIN_YEARLY,
MAX(HIGH) OVER(PARTITION BY SYMBOL ORDER BY TIMESTAMP) AS MAX_YEARLY,
AVG(HIGH) OVER(PARTITION BY SYMBOL ORDER BY TIMESTAMP) AS AVG_YEARLY,
STDDEV(HIGH) OVER(PARTITION BY SYMBOL ORDER BY TIMESTAMP) AS STD_YEARLY
FROM NSEDATA d
ORDER BY SYMBOL" | sed 's/[[:space:]]\+/,/g' > ~/output2.csv
